PC automatically rebooted with Stop Code 0x9c

Hi there.

hmmm...this is the first case I have seen this but I wanna
give it a shot....

Firstly, what did u install/uninstall before last Friday?

Secondly, have you tried updating Windows and drivers?
(just for safety....)

I would also like to know what happens if you use the last
known good config at startup when pressing F8? Does the
error happen again?

I want to know, if you have another machine and the SAME
chipset, can u take out the HDD and put it in that machine
and see if the error occurs?

If not, can you take out EACH PCI card and leave in the
graphics card alone and disconnect CDRW/DVD R/Zip drive
and see if the error occurs? Then slowly, ONE BY ONE
insert each card/drive and see if errors occur, if it
does, then check that card and see what happens.

If all else fails, please see if you can repair Windows
2000 using setup and if that fails, there may be a faulty
MB...but could be unlikely.

Can you see if you can update the BIOS? Well - it's not
needed since it is a HARDWARE error of some sort.

The CPU (or CPU Cache) COULD be faulty but also try this:

Can you disable PCI Bus mastering in your machine? What
happens?

Please let us know what happens, thank-you
