I don't think so the reason is several times when it shut down I would go into the bios setup and check the cpu temp and fan speed both remained normal.
There was nothing at the end I could figure out and I have the MB in the boneyard now.
the things I tried before making this choice was
I changed the power supply
I removed the cpu and the memory cards and cleaned the entire board with compressed air and resetted the cpu with heat paste
and the memory cards.
I changed the video card and removed all other cards from the board.
I used the Western digital drive repair disk on the drive (which is currently running with a different MB).
The strange thing to me is that the unit would run and did run for 4 hours straight while writing the drive to zero's with no problems.
My thoughts is that one or more of the pci slots or controller itself went bad.
I was able to fully load windows 98 second edition (just for the grins) but the system failed as soon as I plugged in my network card which was about 2 hours after the install during the loading of the drivers it locked up (it would never shut down it would just freeze up).
Later I may try to flash the bios but getting a floppy drive that works is rough but most bios updates require a floppy install I checked with abit.
