Helping people with computers... one answer at a time.
Testing for a BIOS problem is probably not possible on a computer with a problem this severe. It may need professional diagnosis.
My computer went dead. I've tried everything, but have come to the conclusion that the problem is either a bad CPU or a damaged BIOS. How can I test the BIOS to see if I'm right on a computer that won't boot and if the BIOS is bad, can it be flashed?
In this excerpt from Answercast #80, I look at a machine that won't boot and the likelihood that it is a BIOS problem.
Well... I will admit that, to me, it is extremely unlikely that it's the BIOS.
BIOS is just some software. Now granted, it can become corrupt - but if it does, and if the computer won't boot, or can't even come up to a BIOS configuration screen, then I honestly don't know of a way to fix that.
It's more likely to be some kind of hardware related issue.
Now, I'm not sure what steps you've taken that lead you to believe that it's either the CPU or the BIOS. However, there are so many things on the motherboard, for example, that could cause the thing to appear completely dead - that it could, in my mind, be just about anything. It could be anything hardware related on that computer.
Ultimately, I really think that the only true solution to a problem that's this severe is to take the machine to a technician. See if they can diagnose, specifically, what it is that's wrong. Then you can make a decision as to what the correct steps are to repair, or potentially replace, the machine.
