Windows XP hang loading agp440.sys

Every time I boot the computer I see the Windows XP logo. It disappears and then nothing else appears on the monitor. Yes, I thought we/I had resolved this problem but it still exist. *sigh*  When I go into safe mode I cant get the computer to boot either. It hangs when loading agp440.sys.

I DONT want to lose the data on the computer. I dont have a backup. There is one HD 2 partitions (C & D) I do want the machine to boot up. I think all of the data is on drive D not including email which is on the C drive.

you need a backup first and foremost.  The easiest way is to fit your hard disk as a slave to another pc and to copy the files and emails of that way.

Thanks for the info! I read a few other people that had the same problem. They tried the solution found at http://support.microsoft.com/kb/324764 as well.

It appears that most hung at the object above agp440.sys which is MUP.sys.
What the hay I will give it a go!

Thanks KCTS!

Thanks for the tip DanCh99!

Since there is only one drive (the C drive) I will have to take the HD out of the computer case place it in one of those HD enclosures and backup the partitions to another HD enclosure. Then return the HD to its computer.

Ha! Who said it would be easy?? LOL!

FYI
I have created a backup for that system. I used Acronis to handle the job DanCh99.
OK I am going to read over again what KCTS is suggesting and then follow through.

KCTS,

I followed the resolution set in http://support.microsoft.com/kb/324764

When I attempt to boot normally I can see the Windows XP banner. The banner vanishes and
the screen goes black. I can hear the welcome music but I can't see anything being displayed on the monitor. When I go into Safe Mode the system now hangs at mup.sys the object above agp440.sys.

I tried the solution posted at Microsoft's site,
a. booted it with the "windows reinstallation cd",
b. ran it in recovery mode (choose option R in the windows recovery console)
c. and ran "chkdsk /r"
Outcome:
CHKDSK found and fixed one or more errors on the volume&
d. Type "exit" and restarted Windows normally.
I see the Windows XP logo. It disappears and then nothing else appears on the monitor. The problem remains. I cant get pass the Mup.sys wont load problem.

I tried:
How to start system restore tool at the command prompt in Windows XP
http://support.microsoft.com/kb/304449
No such luck cant use that since I cant get passed the loading  Mup.sys.
I know that if you startup XP from the disk in recovery mode you can move around a little on the hard drive. So I tried to get to the restore executable image but no such luck.  After getting myself situated within the directory structure I was able to move to the windows\system32\restore folder then locate rstrui.exe but it didnt do me much good because I couldnt execute the file. My guess is that there are some instructions loaded that are not when in recovery mode.

Any suggestions or comments are welcome!

Overnight I ran the Windows Memory Diags (WMD). No errors were found.

Any suggestions or comments are welcome!

Thanks!

I forgot to mention that I reseated the video card before starting the WMD.

I went out and picked up a new AGP video card and dropped it into the box. I still had the problem. I even re-enabled agp440.sys thinking that it may need it. I was wrong.

In the BIOS I found where I can choose between PCI or AGP. I selected PCI and was able to boot up the computer! Doing that allowed the BIOS/OS to select which one it needed not me.

Later on I will put back the original video card and see if that will work. I hope so since the card thats in there is not expensive. It is not a good model.

Cheers!

I reinstalled the original video card. Rebooted the computer. On the monitor I saw the Windows Logo.  It disappears and then nothing else appears on the monitor. In the BIOS I enable agp440.sys and rebooted the system. It hanged on agp440.sys. When I disabled apg440.sys and rebooted the computer the system hanged on Mup.sys.

I took the old video card out and reinstalled the new video card and rebooted the system started!
I enabled apg440.sys and restarted the computer and the system started up correctly.

At this point my guess is that we were having problems with the video card.

I noticed that the BIOS has never been updated. I wonder if that could have cause the problem in the first place? I guess not since there is no onboard video card. Just a guess.

Cheers!
