Okay, well I'm having this problem that happens when ever I boot 'Battlefield 3'. I play about 15 minutes then BOOM I get a Black monitor asking what source should i use (VGA, HDMI ect) and a unresponsive system ( I have to power the system down from the mains in order for me to restart it.)
I checked all the temps they are fine. The Computer runs smoothly when it idles.
