    iMac CPU fans... and other hardware
    I'e been having problems with my iMac. it's a 20" G5 2.0 GHz ALS.
    It's had boot problems (abnormally long)
    the fans will often come on at full speed like it's in open firmware mode
    it won't sleep; just black screen and loud fans, then after a while it'll wake back up if i hit the mouse
    long shutdowns
    external usb drive spins down erratically but still shows up as a mounted drive
    ...and the weird thing is I just repaired the disk ( it said it was bad)
    and archive&installed the system.
    it's 10.4.11

    ok, here's what I did:
    i messed around with the boot order in open firmware to boot from my USB drive
    ...and I can't be sure that's what did it, but it could be)
    also, after I reinstalled the system, it worked fine, then...
    I booted up from my PowerBook in Target Disk mode (FireWire of course)
    and from then on it's benn finnicky again.

    Ever since I got this computer, it's just been a little...

    my PowerBook is far more reliable...

    anybody hav e help?
    anybody have the same problem?

    oh, and this iMac's originally from London, if it makes a difference.
    I use a europe/USA power adapter plugin\
    shouldn't make any differenc though.

    thanks for any help!

    Welcome to Mac-Forums, esteban.

    Look at this list and see if your iMac serial number is included. You might have a free repair part of that Power Supply Issues recall.
