Power Supply? Temperatures? Only you have this issue when you try to play VLC player?

PSU: Cooler Master Extreme Power Plus 600w (RS-600-PCAR-E3), GPU temperature is 30 degree at idol and 60 to 65 degree in gaming. other temperatures are all normal,yeah this happens only playing movies, whether on VLC or WMP

Do a clean install to the newest driver?

 

[soofi]

yup, also did that, now i also came to know, i was doing designing with CorelDraw x5, i selected a color to fill an object, as soon as selected that color became visible on the whole screen and again my system stucked
