I had 2 P4 extreme systems running up until last year. I built them in 2001. Both died within a month of each other. Think I got my money's worth out of them.
Probably just a shorted cap on the mobo. If you have the equipment, its an easy fix.
It was the processor. Tried 3 other motherboards didn't work in any of them. Amazing part was I found the same MB I was using new for a few bucks.
