I built this PC 8 months ago never a problem, i moved to a new (and better) house, after the move i am trying to setup my home network again and i cant get my new PC to stay on. about 20-30 seconds after POST it will turn off by itself, no warning, no beeps. it doesnt matter what im doing at the time either (in Win7, or CMOS setup)it shuts off. before the move everything was fine. Before you ask, NO it did not get dropped or anything like that, i can sign into windows 7 and a few seconds later it will shut off. I bought all top of the line gear for this system cause i was tired of building a PC that was out of date, before i closed the case. PLZ HELP!!! I have done everything i can think of to fix it, checked every wire, and so forth, I have an AS Degree in Computer Science, but have been outta the market (health problems) for several years now so i am a little rusty with todays tech. PLZ HELP!!!
