OT: Need PC MB help!

It's quite possible that the cache supply voltage and the main memory supply
voltage were set to different values while the board didn't know that and
hooked them together. I did that about 5 years back. That same mobo used a
cache simm which could be plugged in backward. That wasn't good either.
Trying to fix the thing will take a lot of time and won't yield results
worth having. Best to follow the suggestions below.
