Help!!
Randomly when on my PC, my GPU stops displaying and the fans stop spinning, I can still hear audio but its laggy. The fan spins up again but does not display. When I reboot everything is fine. This is not linked with any overheating as it happens randomally eg. After half a hour of BF3 , or five minutes or being idle. Sometimes when it happens I can hear a scratching noise from my PC.

My GPU is a Sapphire r9 270x 4gb that I already replaced the thermal paste on. My PSU is a Corsair AX860 and CPU a FX-4300.

Any help is very much appreciated!
