Do you have any idea what might have disturbed your install? Do you remember getting an Windows update message?
The postings I have found seem to indicate replacing the file might help. How can you do that, possibly one of three ways.
If you can boot to the Install DVD, go to the command prompt and run SFC /scannow. Maybe it will find and fix it.
You could also replace the file yourself from within the command prompt. Someone here could probably send you a 32 bit version.
Someone else used a live Ubuntu CD to start Linux on their system and use it to replace the file. A live CD does not install, just runs from memory.
Also, even though I have not done it, if you knew for sure if it was a Windows update you might be able to uninstall it using pkgmgr.exe from that same command prompt.
Another thing, which I saw was tried and did not work, would be to set the bios from PnP OS installed to the other option, yes or no.
Is there anything you can unplug, or turn off in the bios? It is checking some device and causing problems.
My best guess is you got an optional hardware driver
from Microsoft and it has messed up your system, unless you have another suspect.
I remember a tutorial somewhere that talks about starting Device Manager in an emergency situation, I will try to find that.
