    Pretty much I have an issue where sometimes when I boot my PC, the screen flickers on the Log In screen and goes to black. My mouse pointer is still available but that is all , and I need a reboot. Weirdly, when I set Bios to Performance Profile it boots up fine and I can Log In.
    I can recreate the problem by running Unigine Heaven Benchmark and about 3 minutes in , I get a black screen and need to reboot.
    I get the same issue with a different Graphics Card Installed.

    My Build :
    CPU: AMD Fx-6300

    CPU Cooler:Stock

    Operating System: Windows 8.1

    Motherboard:AsRock 970DE3/U3S3

    RAM: 2x4GB GSkill DDR3-1333

    Hard Drive: 1TB S-ATAIII 6.0Gb/s

    Graphics card: NVIDIA GeForce GTX 660ti(also tried ati x1600 pro)

    PSU: 500w beQuiet system Power 7.

    Also I have tested the power supply and all seems fine. Also ran Memtest86 for 3 passes with no errors.
    Some issues I experience are choppy video(fixed on reboot).
