Hey all, I own a 2.33 Ghz iMac that I purchased a year ago, and things have been going great with it so far. I have not yet installed Leopard, but I plan to. On to the problem. This morning at about 7am, my house experiences a power outage... but luckily I have a backup battery to keep it on. The iMac was on sleep mode when it happened, and the battery started beeping, so I got up, turned off the iMac, and turned off the battery. Later that morning when I actually woke up, (power not out anymore) I turned on the battery, and then the iMac. But the second it turned on, the fans are blasting full speed. It is very noisy, and even restarting the computer produces the same results. Any idea whats wrong? Thanks.
