A Byte Of Life

I have the same problem on my Compaq. I found out that the agp440.sys file comes from an ATI video card. I uninstalled the ATI Device driver from Add/Remove programs. Behold, it booted up quickly although my display was a little off. Nothing that couldn't be taken care of using the monitor panel. When I reinstalled the driver, booted to a blue Stop screen.

I renamed the file and it has booted up fine now. Not sure how long this will last though.Everythng seems to be working ok for now.

If it doesn't load Windows -- how do you install the patch?

I tried the solution posted at Microsoft's site, and that didnt work. However the agp440.sys problem disappeared when I did the follwing.
a. booted it with the "windows reinstalltion cd",
b. ran it in recovery mode (choose option R in the windows recovery console)
c. and ran "chkdsk /r"
d. Type "exit" and restarted Windows normally. Now it works fine.

This is a recurring problem for me, and i have reinstalled my OS several times now... does anyone who is experiencing this have similar hardware configurations?

ABIT IST Motherboard 800mhz fsb
1024 mb corsair RAM
nvidia gforce fx5200
seagate barracuda 160GB 7200RPM sata drive * 2
Windows XP media Center Edition
Sony cdrw-dvdr
hauppage pvr-350
linksys 802.11g wifi card
generic pos v-90 modem

My fix was to boot from CD and run a chkdsk on my C: drive. There were
a number of bad spots on the disk (read failures) that were repaired and
when I rebooted all was well.

I am having problems were my PC with get to a point when win xp is loading and then 30 secs in restart it self. On running in safe mode it gets to the agp440.sys and then restarts to start it all over again. I have tried everything apart from from unplugging the mouse as it is a usb mouse, but now I have read this, I will give it go.

But trying the repair I get please enter admin password, and there is a problem, I never entered a password so I think my computer manufacturer must have put this in as it came all installed by Evesham. But whether they will be able to give me this is going to be a different story. So I hope the mouse and patch works as I am not prepared to go down with out a fight and have to re-install XP and loose all my work. (I know I should back up, but there are certain things you forget to back up, e.g. new subscriptions, internet settings, and the odd game save which in games like evil genius would take weeks to do again).

If anyone has any other ideas let us know.

i've got 2 main pc's the first went down last night with the agp440.sys prob and this one went down a while ago with a similar problem only mup.sys instead. for the mup.sys prob i just started windows in VGA mode then put on new drivers for the ATI video card. i haven't fixed the agp44.sys prob yet but both problems ocurred when i tryed to install a particular 250gb hard drive i have

I cannot get the recovery console to load. I boot with the XP CD. The cd loads. The set up program begins to load, but the freezes up. I dont not have a floppy disk so I cant try any tricks with that... Can someone help me?

I would suspect the hardware. You could start with a memory test. Check out memtest86 - you can download a ISO image of a bootable CD from here:

Me too! agp440.sys after installing an ATI video card in my Dell Dimension 4600. Was at a loss and then almost by accident I pressed and released the physical start button on my computer, which shuts down the machine. When I restarted everthing cam up normally. It worked fine until a month later I installed a firewire PCI card. I resorted to reinstalling XP first without formatting the hard drive and when that didn't solve it I reinstalled with a complete format of the drive. I got XP updated including SP 2 a day later...bam I can't boot my system at all...AGP440.sys.

Microsoft's KB article 324764 sounded like a sure winner when I found it but after disabling agp440.sys the boot up in Safe just stopped at the mup.sys file as someone noted previously.

Here is a supposedly a "solution" I found on another forum that I hadn't seen elsewhere, which sounded reasonably credible. I haven't tried it yet. There are apparently a lot of us with the problem.

Found the solution!
At our company we had the same problems with SP2 and agp440.sys on several machines. After several hours of tech support with Microsoft, I found out that the agp440.sys is actually the agp driver for the bios. Therefore to solve this problem download the most recent bios update from your motherboard manufacturer and install them. This should fix the problem in most circumstances.

In my case i just execute the comand "chkdsk /r" in recovery console of windows XP instalation CD.
I think that bad sector of hard drive caused the problem. It stop in video driver when started in safe mode because it can't read from the disk.

"chkdsk /r" solved this issue for me as well.

I also had this problem on my director's computer
and I tried the disable agp440 which worked but rendered
the system really slow. What I did that worked was I rolled
back the driver to the previous version. Chkdsk ran automatically upon next restart and some problems were found so maybe the chkdsk did the trick.

Hey, I was pulling out hair on this; then I realized that it must be hardware-related if my Windows boot disk was hanging (in truth, I learned when I stepped out to lunch that it wasn't hanging so much as taking 30 minutes to boot).

It turned out that I had a USB flash drive plugged into my Dell Inspiron 600m and that was the root of my frustration. Wouldn't be surprised if it's anti-virus related.

So, if you're among those of us who couldn't get Windows to boot (via safe mode or boot disk), then my advice is to first eliminate all external hardware (and as much of the internal hardware) as possible.

Best of luck,
Mike

I am having a problem that is very similar to what has been described in this thread. I am running a Toshiba Portege Convertible. Being a laptop it was not difficult to unplug everything that was connected. With only my power cord plugged in I am still having the same problem. The PC attempts to boot, hangs and reboots itself. In safe mode it gets as far as the ASP440.sys. I called Toshiba. I was told to reinstall from the recovery disk. My last backup is about 3 weeks old. I would hate to lose the last 3 weeks worth of work. It sounds like there are a number of suggestions on how I could attempt to fix this but I must first get it to at least boot in safe mode. Any ideas on how to make this happen on a laptop?

I tried Microsoft's KB article Q324764 solution and that didn't work. Using the listsvc command didn't produce any results.

Anyhow, the agp440.sys problem disappeared when I did the following:

a. boot to Windows XP installtion cd
b. choose option R - recovery mode
c. run "chkdsk /r"
d. Type "exit" and restarted Windows normally.

It's alive!

I'm having the same agp440.sys problem on a new IBM T42 laptop. It came without an XP installation cd since all IBM software is preloaded on the laptop. Anyone have have any idea how I can get into R - recovery mode so I can run chkdsk/r and see if it works for me?

ok... I've got the same problem but just a little worse. Can someone help me step through this?

Safe Mode hangs at agp440.sys.
Start normal and Start last known good conf all lead me to a blank screen... greyed out not blue screen.

I can't boot from my WinXP CD because my pc is set to boot from A: (yep... I've never thought to change this)

I wasn't able to make a system boot disk because the floppy was too small.

I've unplugged everything - even the mouse and keyboard.
Same results.

What do I try now?

Eve, did you reboot while pressing F2 to enter System Setup? Then, change boot sequence normally.

Update your BIOS will fix this problem.

I have a new Dell PC. Why should I have to upgrade the BIOS? I doubt there's a different one to upgrade to.

If I disable agp440, then the hang occurs on mup.sys. Could it actually be related to the previous moduls, which is ntfs.sys?

In my case when i try to run "chkdsk /r" in recovery mode it says that there are one or more problems that are NOT recoverable...... PLZ HELP I DONT WANT TO REINSTALL

hi, im having the same problem atm. it only started 2 days ago and my pc has been fine for over a month since i reinstalled for another reason. But whasts happinging is when i turn my computer on it goes past the post screen and then onto the windows xp loading screen and then that finishes loading , then the screen goes blank and the system seems to freeze or hang and it stays like that. ive tried going in safe mode but that doesnt work, ive also tried useing last good known configuration that worked and that doesnt work.

I think it might be the hardware cause i built the pc. but i havent got any hardware to test it either, like if it the memory or the agp card.

here are my system specs.

asus p4v8x-x socket 478
intel pentium 3.0 ghz
512 mb crucial ram
dvd/rw drive
128mb ddr nvidia 5900xt vga card
160 gig hdd sata
480 w thermaltake butterfly psu

thats all that i know reallly. i recently did install a network card about 5 days ebfore the problem started, but ive taken it out and it still happens , but if it was the problem then why didnt it start earluier and only 5 days after.

i cant even use the recovery console in windows xp installation cd , it examines the hard drtive and then freezes or hangs. then i thought i should jusdt format the hard drive and start again but i cant if do that.

i did install windows xp home on a ide drive and it still does the same thing. and that was a fresh installation. now this makes me think that its a hardware prob.

one think that i did find out that at the windows xp loading screen there was a shourt beep. so i looked on the internet for bios beeps and found out that 1 short beep is a dram refresh failure as the bios is ami bios. but that i didnt have a clue of how to fix the dram refresh failure.

so im really stuck now.

please anyone can u please help me !!! it would be great!!!

thanks

I ran chkdsk /r in the recovery console from the Windows CD and everything...but when the disk checking was done, and Windows booted up, it took FOREVER. Also, from the point where the booting was finished to the appearing of the log in screen, took at least 2 more minutes. This is defintely NOT normal...anyone have any ideas on what's going on?

Again, The agp440.sys issue SEEMS to have been fixed - I haven't encountered another error related to this yet, and I hope I won't. However, the computer still boots inanely slow, along with the loading of the log in screen. I suspect these 2 issues (agp440.sys & slow booting) are related somehow.

Any help would be greatly appreciated.

Is everyone by chance running ATI video cards when this problem occurs?

I'm trying to old a legacy (rage pro) card when I am installing my badger edition XP sp2. It installs, I can move around, and then I reboot, BAM

No KB article fix (recovery console) or chkdsk

Swapping video cards for a FULL install to see what happens

got the same (but worse) problem..

If start windows normally I get a black screen after the Windows XP logo
If I start in safe mode (or any variants of it) it hangs on agp440.sys
If i boot from XP CD and attempt a reinstall, it hangs when looking for previous versions of Windows
If I boot from XP CD and go into recovery console it prompts me to select the installation (1. C:\windows\)
so i type "1" and recovery consoloe hangs.

All methods that everyone is suggesting fail.

I know the harddrive is OK cos I can slave it on another PC.
I did the BIOS upgrade (which included the CPU fix) and it made no difference.

I have a 2k machine doing the same thing. Imho, I'm not sure it is hardware related.
I moved the hard drive to another identical machine and "BAM" got the same agp440.sys stoppage. I can keep trying to boot normal then back to safe mode etc... and after about 5 or 6 attempts it lets me boot windows.
I'm going to try the bios upgrade tomorrow. I've changed out the adp vid card to a pci to no avail.

Ive tried chkdsk /r and it always hangs, i don't even have the option of updating the bios unless i can do that in recovery console, any help would be great, its an compaq presario 2100

Well The bios update didn't work, but reinstalling Sp4 seems to have worked for now.......

Please help. I have the same problem with XP Home but my laptop did not come with an XP Home cd. I have an Xp Pro disk but my laptop didn't load it. The CD spins and then goes into the Safe Mode choices, none of which work. The CD is set as the first boot order.

I have nothing plugged into my laptop. Any suggestions?

I had the same problem on sony vaio...
I tried everything the only thing that work was CHKDSK from recovery console. -r from windows cd.

Tri CHKDSK and then tri everything else b/c its the eashiest way, it finds errors on your disk and fixes em.

OK, me too. Last time I had this damn problem, took me 10 attempts to get the laptop up and running. I also find this problem random. I have been to the Microsoft site and it tells me to put in my Win XP cd and blah blah blah. The only cd I got with my laptop was the recovery cd. Is this what Microsoft are talking about? This is annoying to say the least.
I guess the thing to do is take it, the laptop back to the computor shop and get them to what needs doing.

Well, I tried the MS fix (several times) and it didn't work.

I did a chkdsk /r and it took a while, so it may be the HD is going. My BIOS is at the latest update. When I disabled AGP440 I get a Yellow Exclamation mark agains the controller ( 82815 Processor to AGP Controller - 1131 ) and I couldn't actually update my Video Card until I got out of WIndows and Back in again via the "old disable the AGP440 service" route.

For me, as I have just put a newish AGP Card in the old TUSL2-C MB, I was wondering "what next" when I remembered something about a (AGP and USB fixing) Chipset Utility from Intel, required so that XP knows what going on with the BIOS Chips, even if the Manuf don't have any more updated BIOS's.

See http://www.intel.com/design/chipsets/index.htm, choose your chipset (probably one of those "mature" cheesy ones :-) click drivers and utilities, find the CHIPSET SOFTWARE UTILITY, Select your OP System and d/l the file.

May be worth a try if you have teh same error as me. I will try tonight...

SOLVED IT.

on an hp pavilion 7955. reformatted and performed a fresh install of xp pro, however i repartionioned both hard disks before installing, and installed xp on the slave drive whereas it had previously been on the master hard disk. computer would boot into windows but hung for a solid 3-5 minutes on agp440.sys before starting the welcome screen. physically swapping the two hard drive ide connectors (ie. making the system hard drive master and the other drive slave) solved the problem immediately.

Solved on a Dell Inspiron 5150 using WinXP Pro (system shipped w/ XP home)..

1) Update the BIOS
2) Update the ATI Radeon Mobility to the latest
3) Use Recovery console to run chkdsk /r
4) Use Recovery console to run Windows fix found in artical 324764 http://support.microsoft.com/default.aspx?scid=kb;en-us;324764

Do not jump to the last step, that doesn't work. I did the above steps in this order and it works.

Caught another one ...

I just replaced an old MB with a P4P800-VM.
XP Pro hangs on agp440 load.
disabled agp440 ... hangs on mup load
disabled mup ... hangs on vmodem load ...
seems like the wrong path

System only has 1 USB connection to a hub (nothing on the hub) . Disconnected hub ... no change.

I'm checking into MB BIOS - I believe I'm at 2.54 ... may not be lateset.

I've tried chkdsk /r ... apparently not the fix for me!!

I 've just done the latest updates (silly me) and now my system hangs at agp440.sys. I am running an ATI Radeon 8500 All-In-Wonder. Well after reading the helpful tips presented here and on Microsoft's websites, I have done the following to no avail:

1.Removed extraneous USB items..printer, joystick.
2.Updated the motherboard bios. (old board) ABIT BW7 latest update they have is 2002. *sigh*

I am now on step 3. Replaced AGP card with PCI card. Can't boot normally or in safe mode BUT I can now get to the recovery console and I'm currently running the chkdsk /r and it's taking an extremely long time to complete.

This is better than rebooting every 3 minutes but I don't feel good about the outcome. What can I try next?

Just thought I would add a side comment.
Are you running NTFS?
If so the problem could be directly related to NTFS screwing up and nothing to do with either AGP400 (or its close friend MUP), which simply is the last driver mentioned before the screw-up. If this happens to be the case then booting from floppy/cd/pen or recovery will get you nowhere (trust micros**t to put out a recovery system that won't even let you look at the boot drive).
The solution for me and my few clients has been to get hold of a decent pack of Linux utilities, I've used the Knoppix variant, that can boot without using a hard disk and then fix NTFS.
When you get XP/NT back then I might also suggest going to c_panel/system/advanced/recovery and un-checking the automatic restart. That way you can at least look at the messages. Just don't expect them to be relevant.

Thanks for the info SteveJ. I pulled the drive and popped it into a PC where I could run a full scandisk/chkdsk -r/virus scan etc. After I did all that, I replaced the drive in the malfunctioning box and ran the repair install successfully.

Solution - remove stick of 512MB DDR SO-DIMM RAM.

I had more or less the same problem - laptop repeatedly restarting more and more frequently (over 2 week period), until it wouldn't boot into XP at all without restarting, and then restarted constantly (and hung once) at agp440.sys when trying to boot in safe mode. Tried all of the above and got nowhere (thanks for advice though).

I had 768MB of RAM, 1X 256MB (now in old 512MB slot), and 1X 512MB (now on table, resting).
The system seems stable, if a little slow due to the loss of memory, but at least it's working again. It's an Alienware Area-51m which runs really hot, sometimes up to 80 degrees C, which may have cooked the mem module.

Maybe this will help others out there, maybe not, but worth a try. Worked for me.

I have the same problem as all you fine ladies and gentlemen, in that my wonderfully useless computer keeps stalling (well continuous reboot loop) when it hits the dreaded agp440. I was gonna try and update the bios as suggested, but i cant seem to find the bios update for the motherboard that i have. its a gigabyte GA81dmnf, and gigabyte dont even have that model on their own webiste, so i was just wondering if there was a bios update available for my comp, or whether i should just resign it to the scrapheap(well the motherboard at least:P) answers on a s.a.e nah not really, but i would appreciate any suggestions. nice one.cool.bye.

this is acctually the second time i have experience this problem... the first time i eventually started getting a message along the lines of "hard disk drive failure imenante"... low and behold, i had to send my SONY VIAO laptop to be fixed and have the hard drive replaced.

the idea of the checkdisk seems a reasonable one, and i'm sure it will work... at least temporarily as i had gone through that process with my last experience... in the end it bought me a little more time, but not much more.

my suggesstion to anyone who is able to fix this problem... BACKUP RIGHT AWAY... if you dont know the pain of loosing years worth of info, consider yourself lucky!

Hi i also encountered the agp440 problem, i have got some program which allows me to view the content on the drive (nfts) or something, which is closer to fixing the problem than i was before, does any1 know what needs to be done though? do i need to rename the agp440 file? it says the boot sector is fat12 and the program i was using wouldnt work with it or something. Any suggestions would be most appreciated.

used the microsfot boot up floppy disk set(of 6) and when i tried to use chkdsk it said where is the location of autochk.sys or something, if someone could please ellaborate further i would be most oblidged.

i had an external hard drive that was attached to the computer, when restarting with the hd plugged in the computer would hang up. unplugged and all is well.

HELPPP!!!...I have a sony viaos notebook and it came with no disk...I'm having that hangup when trying to load the agp440.sys...is there anyone out there who knows how to fix this WITHOUT a boot disk?

I know it's probably obvious but my computer was working FINE until the last of the "necessary" automatic updates from Microsoft, afterwhich, it did the whole rebooting/crashing thing.

I fixed the problem by updating my nVidia drivers for my GeForce 5900, but had to keep rebooting my computer until it final rebooted - 45 times it took!

HP Pavilion 752n was constantly restarting, would not boot up, even with Last Known Good Config. When starting in safe mode, the agp440.sys was the last item to show up before a brief pause and the restart. By using the XP disk and going into Recovery Console, I ran chkdsk /r. It took over an hour to finish, but now the system starts with no problem.

We had this problem after a power cut. We reset the power (unplugged power cable from power socket and from back of PC, then waited for it to go "click") and it boots fine now.

My Computer experiencing the same problems but i DO NOT HAVE AN ATI CARD! i have an nvidia G4 MX440 64mb!

and it hangs at agp440.sys when i do safe mode, if i go to last known config, it goes to loading screen, a blue screen of death pops up, for like 1/16 of a sec and goes away! so i've read all this but dont know which way to go! Is my hard drive failing? or wat? i have enough valueble on it and i do not wish to format it!

Can't Install Windows XP in moderboard p4v800
please help












receive whit thinks

hi, glad to see that at least this forum is active. Mine is an old laptop with no CD-Rom drive, formatted it from win2k to Xp through lan. i have a rather similar problem. "windowsdid not start successfully.........." if i chose safe mode, it will stuck at the agp440.sys. If i chose last know gd configuration or start windows normally, the black and white ASCII bar will load and hang.and the com juz stays there permanently. Ie. i can't even get to the desktop screen. i have solved this problem before when it was in win2k but i forgot how to. thanks for any help given.

*edit* the black and white ASCII bar will load and hang *edit* the bar has finished loaded but it juz shows the grey bar. it does not proceed on to the windows xp screen

what is this mysterious 'CHKDSK /R' process that helps everyone out when their computers hang on the AGP440 system file. Once I am in recovery mode, how do I run 'chkdsk /r'?? Please help!!

i have the same problem. when XP try to load agp440.sys OS hangup and must press Restart on PC :(

in my PC i have installed 98 and XP. from 98 i delete pagefile for XP and hibernatefile (if not wrong - hibfile) then XP start normal ;)

good luck
Svetli, Bulgaria

I have a PIII Dell Latitude L400 with the never ending boot cycle! Same problem as all the others. If I choose safe mode I hang at AGP440.sys then retart automatically.

I have tried renaming the agp440.sys file - Hangs on Mup.sys
Tried reinstalling - cannot find CD rom and wont autorun for cd either.
I have run the chkdsk /r - Tells me to run scandisk.
Run scandisk - found 8 errors and reportedly fixed them.
also ran a surface scan with no errors or bad sectors.
I already have the latest BIOS v09 but have reflashed twice - says done.
I have copied the agp440.sys file from another machine.
I cannot run the recovery console - I boot up with the 6 xp disks and then choose "R" - The system goes blank, then reboots.
I have tried running the laptop through an external monitor.

I would like to disable the agp440 service properly but cannot run the r console? What more can I do?

I just encountered the "hangs at agp440.sys" problem for the second time in my life. Both times it was related to defective peripheral hardware. The first time it was a bad CD drive that I fixed by first removing it from the computer, and then using another computer to update it with the latest firmware release (yes, CD drives have firmware updates just like motherboards do).

The second time was a defective USB flash drive that I had left in the computer's USB port when I shut the machine down. When I turned the machine on the next day, it hung at agp440.sys in safe mode. Even the Windows XP CD wouldn't boot past the "Setup is Starting Windows" message. I started to remove all peripheral devices and discovered that I had left the USB flash drive plugged in. I pulled only the USB flash drive and the system booted just fine.

If you can't boot to the point where you can run a 'chkdsk /r' then I suggest you try unplugging or replacing each peripheral hardware device one at a time until the machine boots. No device is too small or insignificant to remain above suspicion.

Good luck. I've felt your pain.

another days work and the machine is alive again.

I tried all the recovery console tricks suggested( when I finally was able to run the recovery console) Had to use another CD rom drive! No Luck

I went for a reinstall - then hit repair when it picked up the previous version. Didnt restore completely, more like reinstalled over the top of the old install. Saved the data though - just had to move it from the old profile, but cleaning up and reinstalling programs is a pain.

Good luck anyone else still frustrated!!

agp440.sys might be a red herring. Check our (remove) USB devices and try again! If this works you have an iffi USB connection (Mobo fault or device).

Had this problem once before now and remedied it by Ghosting all software off and formatting/rebuilding. However, recently backed up all software and tried to duplicate the problem. This issue of constant restarting occurs when the Master Boot Record is damaged or is referencing unknown or corrupt drivers. As many of you have found out it could be as simple as a USB mouse, Video Card, or something more complex like missing drivers. The way I replicated the problem was to install all the latest updates, then use the windows XP CD with SP1 to revert back. This causes the boot record to corrupt.

The chkdsk/r should remedy your problem. If not, try booting to the recovery console and typing "FIXBOOT C:" or "FIXMBR"

I had this problem after I uninstalled the HP Photo & Imiging Software 2.0. I disconnected everything down to the keyboard. I then rebooted and the system came up. I connected everything one by one and when I connected the CD ROM it failed again. I disconnected the drive and then I went out and reinstalled HP Photo & Imiging Software 2.0, and it fixed my problem.

chkdsk /r worked for me.

Thank you to all!

this problem comes up at least 3 times again tonight. use the chkdsk /r once, but did not fix the problem. did a windows restore back to this afternoon, works a while, but when i get back homw, it happens again, unplug usb mouse, and restart, it works fine now.

so i think i still don't find the real reason/solution for this problem.

My Inspiron 9100 was hanging on agp440.sys So I ran the chkdsk solution. The system found errros and corrected them. I rebooted and found the same hang problem. So I rebooted from the Windows CD again. I left the room and when I came back, the Windows logon screen was up. I logged on and a window wss loading like I had the Palm install CD in the disk drive which I didn't. I am going to run virus and defrag and backup, whew.

I have the same AGP440 issue, but I can not reinstall windows or even bring up the recovery console. It also hangs! I have a toshiba 2435 laptop with the latest bios and disabled all features possible on the bios.

Please help.
desperate@laintro.net

My laptop has a dlink wireless pcmcia card which has been there for so long, I totally forgot about it. After trying all the above solutions with no success, I happened to see the card, disconnected it, my nightmare dissapeared!

I have an IS7 mobo (P4 1mb cache)

I have done the following but still wont work:

1) updated bios to 22
2) unplugged all devices
3) re-seated RAM
4) ran chkdsk /r
5) disabled agp440.sys
6) set mobo defaults to fail safe

After doing all this it still hangs...cant even get into safe mode.

Anyone have any idea?

Ive finally given up trying to fix this problem and taking the 'easy' way out by doing a repair of the windows OS. I will post back when its done.

My personal take on this problem is related to SP2 and my mobo IS7 as it seems that there was some incompatibility. Over time this lead to disk corruption and hence forth ntldr.exe became corrupt (fixed by replacing) then agp440.sys corrupts.

Now Ive flashed the bios to the latest version hopefully this problem wont come back

Well that didnt work! I now get a BSOD on bootup with error code 0x0000007b although on closer inspection I think i needed to press F6 during install to put the RAID drivers on...which I cant do till tonight as im at work.

Im pretty sure this should fix the problem as it goes past the agp440.sys file.

I think the moral of the story is Im never going to install SP2 ever again on my machine as it ran fine for over a year on SP1....SP2 3 months tops

I have this problem too, but I can repair XP and everything is hunky dory, but when I run Windows Update and applies the security patches released since SP2 this problem reappears.
I´ve tried everything but nothing works.

Had this problem on a Dell Optiplex 170L w/BIOS version A07. Flashing to version A09 did the trick for me!

My case: IBM Thinkpad A30, 512 RAM. Regular boot would freeze on the XP logo screen after about 7 secs. Safe mode would get to the AGP400.SYS and freeze with no disk activity. Unable to boot from CD -- it too would freeze when it got to the "Starting Windows" message (prior to the R option). I have a second hard drive in the UltraBay. Pulled that out and voila! Normal boot. I am SO glad I don't have to reformat and reinstall!

Spoke too soon. It was one lucky shot. Now it doesn't work with the second drive in or out. I used Acronis to kill and recreate the partition on the second drive, then swapped the drives, using the now empty drive as the main one. Then I booted off the CD and the install works normally. I went to the Recovery Console and did CHKDSK /R, expecting that to do the trick, but when I swapped the drives back around, same problem. So, at this point I think it is probably some sort of corruption on the #1 disk that is beyond CHKDSK to repair.

Has anyone had this problem after a windows repair? i had some niggly little problems with my install so i ran a repair because nothing else could fix them, then when I went to reboot it would just hang then reboot after the winxp loading screen, i've tried everything in this thread but it hasn't worked. I guess it could be my graphics card becasue i've pulled every peice of hardware out thats not needed for the computer to work and I don't have another AGP card so I can't check if it is that.

I think Windows is checking the disk for Bad blocks. --

I've attached a SATA disk that I know has bad blocks on it to a supermicro motherboard: x5dal-tg2 with on board silicon image Si3112r SATA raid.

With the disk attached and booting in safe mode it hangs after agp440.sys and normal boot the screen shows the windows xp logo then goes black. The disk light for the SATA disk with the bad blocks remains on (disk activity).

If I boot windows without the drive it's fine.

Once at the desktop if I stick in this drive the light stays on and doing a disk scan in disk management hangs.

The event viewer is filled with errors about bad blocks on this disk.

Does anyone know of a way to stop Windows XP from bad block checking a disk. Basically I don't want Windows XP to do anything to the disk except spin it up, check the model number, and show it in the device manager.

I don't want to mount it, autorun it or anything.

The disk has bad blocks on it, I know that, and I want to run OnTrack easy recovery against it.

I've got me an Epson Picture Mate, and when I connect it to my Toshiba Satellite, it shows that it have found a new USB device, after that it just restart by it self and keeps doing this even before getting to the window user's screen. I tried to load in safe mode, and it stops when it is loading the agp440.sys drive. All the problem disappears when I disconnect the new printer from my laptop. It runs perfect.
Can anybody tell me how to solve this problem and be able to use this printer connected to my computer?

Thank you!

for me it was NONE of the above.

I pulled the HD from a P4 Compaq and dropped into a flaming new AOpen p4 Prescott 3.2E.

Boom...it didn't like it at all.

here's my fix (if you moved the HD from one machine to another)

i got a new HDD 250 Gb and i wanted to install winXpHomeEdition on it (clean install)
That's when the problem begun!

I have Abit AI7 MB with Radeon9800pro P4 3.2 HT

the nice part is that on the same computer i have another HDD 80 Gb that boots and works just fine even with the 250 Hdd attached. The 250 second hard drive works fine also until i boot from it.
Basicly I have 2 OS on diffrent HDD (one works ONE DOESN't)

I conclude that
