PROBLEM: Lost or corrupted system driver(s)
EQUIPMENT: Custom-built PC, 2.4 GHz, 247 Gig hard drive, 4 gig RAM, Windows XP Home Edition installed two years ago.




I turned on my computer last evening and got this error message:



Windows could not start because the following file is missing or corrupt:

system32\DRIVERS\pci.sys

You can attempt to repair this file by starting Windows Setup using the original Setup CD-ROM. Select 'r' at the first screen to start repair.



That by itself didn't work. Searching the net I found this fix, but it was under a WINDOWS 2000 forum topic: It explained how to use the Recovery Console to get access to the C drive of the computer. I did that and typed this at the COMMAND PROMPT:

expand G:\i386\pci.sy C:\winnt\system32\drivers /y

I had to type this several different ways (getting the message "access denied" repeatedly until I finally got the syntax right (I think) and got a message that the file couldn't be found. The CD-ROM with the Windows installation disk was identified as G. I'm not sure if the file that couldn't be found was on the CD or on the Hard Drive. But it occurs to me that the file paths on a Windows XP might be different from those on Windows 2000 or NT.

Does that DOS command look right? I can't see my Windows folders, so can some tell me the exact path from C: to the drivers file in System32? I'd be very grateful.

Thanks,
SD

pci.sys files are here, generally:

C:\I386 (if on your computer, early version here)

C:\WINDOWS\SYSTEM32\DLLCACHE (any updated version)

C:\WINDOWS\SYSTEM32\DRIVERS (any updated version)

So your filepath should be C:\WINDOWS\SYSTEM32\DRIVERS

See how you go.

You didn't type the full filename pci.sys and I don't know if the file on the XP Disk has to be expanded.

The file in I386 on the computer is NOT expanded.

The copy command may be more appropriate.

copy G:\i386\pci.sys C:\windows\system32\drivers

If that's no good, try copying from the DLLCACHE

copy C:\WINDOWS\SYSTEM32\DLLCACHE\pci.sys C:\windows\system32\drivers

Be aware that even if you get the file replaced, you may get further errors and you will
need to run the system file checker, if that is the case.

expand G:\i386\pci.sy C:\winnt\system32\drivers /y

You have "underscore" missing, to start with.
Also...."winnt" doesn't exist in XP.

Correct command will be:
expand G:\i386\pci.sy_ C:\windows\system32\drivers /y
"Underscore" means that the file is compressed.

Ignore this one, you've amended your post and I didn't see it, in time.

Just wanted to know if you could confirm whether or not the file on the XP Disk is compressed or not.

I made a typo, so I corrected "winnt".
Yes, that file on Windows XP CD is compressed.

Thanks guys. The last DOS command did the trick. It got the necessary file from the installation disk, expanded and installed it. Unfortunately upon rebooting I got the original error message, only this time the missing driver was NTFS somethingorother. So who knows how many drivers I need to reinstall, or for that matter, what other files may be missing. Still, it's a start!

Now i'm wondering what caused this? Is a virus the most likely culprit, or the fact that power in my home went off briefly earlier in the day, or is it the MMPORPG that crashed several times that day?

What was that filecheck thing you mentioned. Is there a faster way to reinstall these drivers than one by one?

Thanks again.
