Last night i was just about to get off my PC,i was unplugging my second monitor and lamp when doing so cause the lamp to spark, like the light bulb busted,and it cause my GPU to stop working,cause screen went black.i powered off my PC then restarted it my GPU fan ran loud and no video detected.I plugged my second monitor and lamp back in they both work just fine,i opened my PC and checked to see if there was any burn marks and there was nothing work with the card.I took out the GPU and PC boots up like it should,plug it in PC still powers on but GPU fan runs loud
fixes i tried where taking ram sticks out and replace same thing, my GPU is a AMD HD 7750
