Everytime i on my pc, the fan on the graphic card start spinning. I'm sure its not lose wire or pins. But the monitor screen says no input. Then i have to hold the power button to off and then take out the graphic card and put it back. Then only the monitor will on. I already performed a clean install of the latest driver yesterday so it should not be the driver problem. What could be the problem? gtx 750ti and a 650w psu.
