When ever i play games like tf2 or csgo after a few minutes and sometimes an hour or longer my computer freezes everything stops moving sound just cuts off and i can't seem to figure out why. http://puu.sh/paEHZ/fc1bf9ad12.png
that's my specs
I did apply new thermal paste to my cpu and it did not seem to helpI'd run memtest86 and see if you have an issue with RAM. RAM issues can be MINOR and take time to show up or can happen faster. Additionally a hard drive or SSD that has issues can use swap space and run into troubles and read back info to system and cause INSTABILITY, freeze ups etc. Crystaldiskinfo is what I use to check hard drive health. Additionally look in the event VIEWER of windows and see if there are any errors or warnings that give you any insight as to the problem your having. Additionally these 2 games are probably played through the steam client. I have both of them for steam and you might have to uninstall and reinstall steam clean. Lastly video drivers can cause issues, so make sure you have latest graphics DRIVER. Lastly voltages you will want to make sure are all within spec as for a low voltage output power supply could drop out the system during gaming when video card and game ( heavy system activity = HEAVIER load ) loads it down heaviest.
