basicly I was playing a game online with my friends and my screen suddenly went blank as if nothing was connected to it. I pressed the power button on my pc to turn it off and it wouldn't turn off as if the button didn't function, I also have a restart button and it did the same thing. I had to unplug the cord and plug it back in and then turn my pc back on, same thing happens where there is nothing on the screen and also my mouse and keyboard don't light up or do anything when I hit a button.

gforce gtx 670 gpu
amd phenom X4 ll 965 cpu
a older discontinued gigabyte motherboard(ill try to find it again)
mod x stream pro 600w power supply

those are the parts that I know off the top of my head. the parts have always been kept cool and never hit their max temps. about a week and a half or so the power out in that room would shut off because there was to much stress on the breaker so we had to keep switching it back over to keep power to that room. this happened about 4-5 times and im wondering if that could be the cause. thanks guys
