I was playing a game of civilizations the other day, and my PC just turns off. Now when i turn it on there is no beep code and im getting power to my case fans, but none of my peripheral or even CPU fan spins up or gets power. I unplugged everything but one monitor (i tried onboard and GPU) and a keyboard but no joy. I've done a bit of troubleshooting before but always with beep codes. I'm not sure what to start with. Does anyone have any ideas?
