G5-166 turns off after POST - Help please

    My girlfriend's PC has started playing up. It's a Gateway G5-166 so pretty
    old - 7-8 years perhaps. It basically works but frequently when booting up
    the machine will get well into the POST, certainly after the memory check is
    complete, and then suddenly the whole machine just turns itself off. This
    happened today, probably 10 times in a row.

    I tried again and pressed F1 to go into BIOS setup, changed nothing and then
    exited, saving (non-existent) changes. It then continued to boot perfectly.
    A couple of hours later I needed to use the machine again and powered it up.
    Same thing - failed to boot, retied with F1, save and then it booted fine.

    Does this imply a failed motherboard battery or something else? I'm not a
    hardware techy although I have added more memory to take it from 32MB to
    256MB but I'm not sure about doing other mods. The problem does not seem
    related to the memory upgrade, as that was performed a couple of years ago
    and the boot problem has only been occurring in the last couple of months.
    If it is the battery, how easy is it to fix?

    Thanks in advance for any thoughts and suggestions.

    Check that all of the fans are operating correctly; clean out
    the inside of the box with a can of compressed air; check for
    overheating; check for bad RAM.

    I'd replace the battery first (as well as a good cleaning). Usually a piece
    of cake to do.

    Definitely replace the motherboard's C2032 3v coin-sized Lithium battery. It
    should cost no more than $2 or $3.

    Next on my suspect list is the power supply. After a good cleanout of all the
    dust bunnies, of course... Ben Myers
