Hello, my pc recently crashed mid game and showed a bluescreen without any text, I just closed off the pc by force and left it. The next day when I powers up my pc it said 'no signal' on my monitor. My components looked alright, fans were spinning, keyboard lit up. My monitor and HDMI cable are fine, I tested it, I replaced my CMOS battery and cleaned my video card. Now it is displaying a code 79 on my motherboard, an Asrock Extreme4 970. Anyone have an idea? I need my pc to study and I have tried everything and I don't know what to do with this code, on the FAQ it says something about CSM initialisation.. Thanks

did u clear the cmos using the button on the back of the motherboard...
Well I removed the battery so that does the trick too I think, but how should I clear CMOS correctly? Turn all power of, remove cable and drain power by pressing on button, or should I just press it while it's on?
