Now when I am playing for example in Test Range on BF4, it lags (even in low settings), also on online servers. FSX runs good. BUT on BOTH games that I tried in about 20-70min the computer just shutdown by itself. I put the EVEREST Ultimate edition and none of the CPU or VGA sensors go over 50C. All other temperatures are kept normal usually 37C.
Why my computer shutdowns unexpectedly?

i had a problem when i built my pc with the memory timings (cas , latency etc.) and it was shutting down. I had to manually set them through BIOS. It took me a month to figure it out. But i guess you have already done it?
