I was overclocking my card following what other people have said, I over volted aswell from 0.975 to 1.100 and over clocked to 900 core and 2270 memory, I was stress testing with EVGA OC Scanner and had no problems, I t was getting pretty hot (88oc) and and all of a sudden while stress testing it shutdown instantly and made a sparking noise which was pretty loud, my room was smelling like burning for a minute and I took the computer apart and was sniffing around and couldnt smell anything, the power supply looks ok when looking from the outside at the inside. i dont want to put it together and break something else if something is broken, please help. I will answer questions asap
