I need some advice here. I'm not a computer expert but know a little and have learned a little more, already, from searching the threads here. Last night, we had a lightning strike. when the power came back on, my pc was dead - no lights, beep or anything. It was connected to a surge protector, and everything else on the protector is fine (printer, router and monitor). I already replaced the PSU, and still nothing at all. I disconnected the DVD drive and HDD and took out all but one stick of RAM and still nothing that way. Is this most likely a motherboard? I could not find any visible damage anywhere.
