I have a computer system I built myself. I contains a MSI 760GM-E51 motherboard with a AMD Phenom II X4 processor running at 3.2ghz. I also have 8 gb of DDR3 (1333 mhz) ram, a EVGA Nvidia Geforce GTX 550ti video card, a 1 tb Seagate Barracuda hard drive. I am powering everything with a Thermaltake 600W power supply. Anyway, the system has been randomly shutting off on my. It completely loses power. It started doing it while the system was under load when I was gaming but once it lost power after I had booted it and walked away from the system for a bit. All of the fans are working so I don't think heat is an issue. I have 3 120mm fans running inside the case and I just recently took the motherboard, processor, ram, power supply and video card to a local repair shop and retailer and had everything tested. Nothing failed. The srangest thing about all of this is after the system fails, most of the time all I have to do after it sits for a while is unplug the power connector from the motherboard and plug it back in and the system will boot up fine. It powered off on me today and after it sat for several hours and it would not start up, I opened the side of the case and pulled the plug, reattatched it and the computer booted fine. As a matter of fact, I'm typing this post on it as we speak. I have placed an order for a new motherboard but I wondered if anyone had any experience with something like this in the past and could shed some light. Thanks for any help anyone can provide.

Sincerely,
Jeff Brunn

You might want to try out a different power supply.

Did you check temps? I would suspect the power supply, just for the fact that you had to switch/unplug the psu to get it to power back on. Most computer repair shops will have a PSU tester (we do) that they can hook up in 1 min and let you know if your voltages are in range. Find one that won't charge you (I don't) :)
