Hey all, Just before I start, my AppleCare ran out earlier this year in February, so I'd rather not have to take it in the Apple if I can avoid it. So, I left my iMac on overnight last night to finish downloading some stuff. I woke up and all our clocks are flashing, so we must've had a blackout. Anyway, I went to check the progress of my downloads, and the iMac was off. I pushed the power button and nothing happened. No fan noise, HDD noise, nothing. I've been trying for almost two hours now and nothing is working. I've already tried resetting the SMC and checking the RAM modules, which seem to be fine. I can't try anything else (ie resetting PRAM) because it won't turn on to boot. Nothing happens. Can anyone offer any advice? Thanks!
