[QUOTE="esteban, post: 549803, member: 43745"] 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... weird. 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! [/QUOTE]
