You need a battery backup with surge suppression and line conditioning.

FWIW, I have another computer (DELL) plugged into the same outlet and it's never had a problem.

The computer with the problems is one I have put together.
I did put a new PSU in it a few months ago.

I forgot to check yesterday, but tonight I'll take a closer look and post more hardware specifics.

Also, what's "line conditioning"?

Thanks.
