    What happens when a processor goes bad?

    Will the computer - G4 - still boot up?

    If the processor goes bad, the computer won't boot up. There is nothing there to process all the information.

    In order for a computer to boot, you need at least a mostly functional motherboard, ram, and processor. In some most cases (depending on your bios) you also need a functional video card.

    They have a form of BIOS now. Or something similar to it.

    It still has firmware, thats why you have to use bootcamp to install Windoze on a intel-mac

    no the computer should turn on, but after that its questionable. The motherboard has a built in processor, comparable to a cmos, to get everything on and get the processor going. a dead power supply would make it not turn on at all.

    also a side note, a power supply and a motherboard is all you need in some cases. It will beep at you signaling problems. Also in some cases I've seen a computer refuse to turn on without a PS/2 keyboard plugged in.

    You need to install BIOS onto the Intel Macs if I remember right since they utilize EFI instead. Both are a form of firmware, but are specific types of firmware.

    If I remember correctly the EFI emulates a BIOS for xp/ other operating systems, not that that matters really though. Just pointing out EFI is always in control.

    this thread is getting way off topic...
