So I recently bought the msi gtx 750 ti twin frozr and when im playing a game my monitor randomly says no siganl detected. The computer is still on the graphics card fans are still spinning but the monitor cant get signal so I have to restart my pc. My psu is powerful enough for the card (600 watt) so what do you think it is, my next guess is the card is getting to hot but it only runs at like 65c. I've tried HDMI and DVi still same problem. Please help
