So basically, I removed my 750ti as I'm selling it to upgrade in the future. In the mean time, I want to be able to run my PC on the integrated graphics inside my i7 3770k. Whenever I turn the PC on, there is no display on the monitor. I've tried removing the battery from my mother board(ASRock Z75 Pro3) and the problem persists. I've tried both with an HDMI and also a VGA cable. Any help is appreciated.
