Ok I accidentally didn't put the problem on the right place. I built a custom pc about six months ago, and it runs an AMD a series 2500k cpu, amd 7770 hd graphics card, msi motherboard, and thermaltake power supply. I was playing bf4 like any other day, and my computer just turned off. The light on the power button was blinking, as it does when it is asleeI unplugged it and tried to turn it on. I heard a loud pop, and It wont turn on anymore. I had just recently downloaded dead space at the time.
