Screen flashes black randomly

Hey, guys, i have been experiencing a problem every since i got my GTX 670 and installed it. After that i accidentally installed a hd graphics driver for my I7 3770K. Then my screen would randomly flash black and then be normal again. You would think that it was because i had installed both the hd graphics driver and the 670 driver but in the device manager under display adapter i can only see the gtx 670. I use HDMI. Thanks

  1. Make sure you have "show hidden devices" selected in device manager.
