So last night I was playing around with my core and memory clocks, due to me having a GTX 750 TI I cannot change voltage or power consumption, and I believe I either massively overclocked or underclocked my GPU because when I stress tested the program my display driver crashed and then the entire screen started flickering with artifacts. Then, the whole system crashed. It restarted itself and when it reached the Windows 8 login screen it crashed again. It continued to restart and crash until eventually the Windows advanced startup option came up. I chose to reset my computer to factory settings. After this my computer worked fine, but when I tried to open a game, my screen went a solid pink color then went to black and again started the restart loop again. The only way I can get out of this restart loop is if I put in the GPU driver disk that came with my pc. When I do that, I can get into Windows fine and use the computer normally, but if I run any gpu intensive program, the entire computer crashes and again gets into the crash and restart loop. My system still detects my video card, and can identify its core clocks, memory clocks, etc.. and their all on default settings. I really hope my video card isn't dead, if any one could help me out I would appreciate it greatly.
