I recently built my first tower and everything was fine until yesterday. I narrowed down the problem to the GTX 660 TI card I installed. The original problem was that it would say"Windows is Starting Up" then go black with the message "HDMI 1 No Signal." I started it in safe mode and disabled the GTX 660 TI and have been running on the integrated graphics. Is there anyway to repair the video card, or should I just replace it?
