It does have the syptoms of a dead motherboard, yes. And motherboards go alot more than processors do. Are you sure its not just your video cable? Do you have an external card? Or are you using onboard.
Onboard. The main problem may just be that the BIOS is dead.
So the BIOS not working means that it is indeed a motherboard problem right?
If so, I'll just try to buy a new mobo.
