Hey guys, i built my own pc about 18 months ago and have never had a problem until last week when it started to freeze. This freeze only happens when im playin ggames, It loses signal to the monitors and the last second of sound loops. Ive taken my case off and cleaned everything out removed and replugged everything. Still happens. Also my temps at peak through games and stress tests are 55 degress.. So definately not the issue.
On a side note, ive tried running memtest. I have it on the usb but when i try to boot from it through the start screen (f12) or change the boot drive (DEL) the screen freezes and i cant change a hting but its stuck on the start screen and wont budge. Any ideas will be helpful, thanks guy.
