Okay so I have a strange one.
Whilst idle or gaming (though not at particularly stressful points my screen when flicker. Several pixels will displace ( Part of A dialogue box in the bottom left may appear near the top right of my screen for example ) then the PC will crash entirely.
My first thought was temps, so I checked, ran prime 95 etc and nothing above 60 under 100% load, and noticed something peculiar. If the flickering starts; and i start prime95 and put my cpu under 100% load it then runs fine, no flickering and no crash.
I'd assume this means the voltage when idle to my CPU is too low? Just thought I'd get a second opinion.

thanks guys
