Last week, he bought a new processor (same specs as his last one, just a different brand) and installed it. When he tries to boot up his computer, he can hear the fans starting but the computer doesn't start all the way. He thinks it's something wrong with the BIOS or the battery that powers the BIOS, but he really doesn't want to take it in and pay $30 for the diagnostics.
I talked to someone else and he said it might be the wrong processor frequency.
So, granted that I don't know the kind of computer or whatever, what sounds like it would make sense? Do you think it'd be worth it to replace the CMOS battery or get a new processor, or should he just give up the $30 and get someone who knows what they're talking about to tell him what's up?
