Recently my PC has been losing it's display and becoming unresponsive at seemingly random times (although it happens more often when I am running a game). Basically what happens is I will be playing a game or sometimes just browsing around and my monitor will suddenly go black and then tell me that no display is connected. Resetting the monitor and re-plugging the HDMI cable from the monitor to the graphics card has no effect. The only way to get a display back is to hard reset. The only other symptom that I've noticed that could be related is that when I first log in to the computer the display will flicker for a second or two which it never does otherwise. I've very recently ensured that my graphics driver was up to date. System specs to follow:
Mother Board: ASUSTek P8Z77-V
CPU: Intel Core i7 3770K
RAM: Mushkin 8GB DDR3 2133Hz
Graphics: Radeon HD 6970 2GB VRAM GDDR5
Storage: Western Digital 2TB HDD + Crucial M4 CT128M4SSD2 128GB SSD
*Liquid Cooled GPU and CPU*
Realized I was running the windows "Dream Scene" process that allows you to run looped GIFs as wallpapers. Just disabled it. Will see if this solves the issue.
