Help! desktop will not boot

Since it will not boot, have you tried replacing the little system battery that starts the Bios?

I did replace that battery. It did not help.

I got it to boot about a week ago by changing the boot drive in the BIOS from drive zero to drive one. (Zero then one did not work.)

Have you tried replacing the Video Card? We had several video cards in the older computers at work overheat. They will lock up the whole system. They will also often make the diagonal lines you mention -- classic symptom.

I use the onboard video but I could try a card. It has been running for a few minutes less than ten days without locking up since I set the FSB to 100.
