So last night at about 4 a.m. a thunderstorm entered the area and my wife woke me and suggested I power down all the computers in our office in case a lightning strike causes a power spike. I blearily stumble to the office and shut down her windows machine, her iMac and then my iMac 27" and once everything had shutdown normally I unplugged the surge suppressors to the AC current and went back to bed. In the morning I reconnected the surge suppressors, powered up her windows pc, the 21" iMac on her desk and then proceeded to my own machine. Reconnect the surge suppressor, connect the computer to it - verify power is getting to the suppressor and press the power button on the computer. Nothing. Tried resetting the SMC and no joy. No lights, power or sound. Took the memory access door off and insured the ram was seated properly. It was but pressed them a little more firmly into the slots - there wasn't much in the way of dust but blew out with air duster anyway. I let the computer sit on the desk while at work with no AC power attached and tried again. Nothing. Well that was unexpected. Here apparently are my choices: -My applecare ran out 2 years ago -it's a corei7 imac 2009 with 16 gigs of ram -I'm still pretty pleased with the performance but this is a crossroads. -I can bring it in to the apple store for potential repair action but since it's most likely power supply or motherboard it's going to be $$$ -This could be more spendy than I expect if it's power supply/motherboard and video card. If I did take a voltage spike I could be replacing more than one component internally. -I can look at another i7 iMac (a refurb in all likelihood) -I ended up spending a great deal of expendable income on my replacement external hard drive array (5TB) just last week. -So any solution is going to have to wait a while. I'm pretty much all set up Mac for my recording studio stuff so going Windows while a huge change of gears would mean retooling pretty much every piece of software I own. So I'm thinking of still staying Mac. But I'm concerned that the last two Macs I've had have not lasted as long as the first two I had. I get 5 years out of them or just under and wham. Done. Anyway. Thoughts?
