I have win8 with media center on CI3 with Gbyte GT610 installed. Randomly when media center is full screen,(only in full screen) the display flashes black. This can happen at any frequency from 1 per second to 1 per minute. IT is random. When the MC is windowed it stops. I have the latest drivers installed. Have removed and reinstalled MC. Removed and reinstalled the Video card. It only happens when the computer is full screen on MC. I have disabled screen saver, power management blanking screen, display brightness auto control. I have my tv adjusted to turn off the over scan cropping so my computer desk top fits the screen. Any ideas?
