Windows can not load because c:\windows\system32\pci.sys is missing or corrupted

[manne]

I awoke this morning to find that my computer was running
very slow, I dont just mean opening programs, I mean my
mouse cursor, everything. So naturaly I reboot and when
Windows (XP Pro) is supposed to load, a screen comes up
saying something like " Windows can not load because
c:\windows\system32\pci.sys is missing or corrupted" I
tried to fix it using the install/repair thingy on the
windows cd but either it wont help or im not talented
enough to use it. Could someone help me to try and fix
this please?

Windows does not come up at all. How do I paste the
missing file?
