I’m rather curious as to how a computer can just die sitting somewhere for a week without being used, because I’m clueless. I’ve taken the following steps, but I’m still in the dark:

1) Verified that graphics card was working in another computer
2) Removed all expansion cards
3) Removed and tested all three sticks of RAM
4) Cleared CMOS & removed CMOS battery.
5) Visually checked for anything out of the ordinary.

So far, not good.
