I've been having issues with my Gtx 660 such as crashing, computer rebooting when I plug in a HDMI cable into the 660. it's stopped working about a week and a half ago. I have no idea if it's a driver issue or a hardware issue I don't have amazing computer skills so I can't figure out what is wrong with it. If anyone can help me with my issue that would be very amazing thanks.

Sorry if this is the wrong forum or place to post this.

Thank you
