    So I've been given an iMac that may or may not be fixable.
    It's a 20" white flat panel iMac (not sure if intel or late g5). I don't know how to identify exactly what model it is if I can't even boot it, which makes fixing the problem even more difficult. When I boot, I get the chime and sometimes i get the questionmark folder but usually just a white screen and some slight beeping noises.
    I've tried resetting PRAM (holding cmnd+opt+P+R on startup) and it reboots, but there is no difference
    I've tried booting and holding power, I get a loud, long beep and a restart, but again nothing
    I've tried power down+ take off cables, wait 15 seconds, plug back in and it automatically restarts, but to no avail
    I've tried booting off an old OSX 10.4 Tiger DVD, and the DVD drive makes some sound but no boot. I've also got a bootloader i made for another computer that might help that I can boot off of.
    Anyways, can any of you offer me advice as to how to fix/identify/anythign else this iMac, as I'd really like to get it working soon? I only hope the logic board's not fried.
