I had a blackout and now my mac doesn't turn on. the power on my whole block went out. I think its on a surge protector. When I go to turn it on it turns on but no chime or load, the hd work on my g3 imac so that can't be it. I hit the pmu button a couple of times but nothing I checked the hd, ram, battery, and power cord but nothing. Please tell me whats wrong.
