i play world of warcraft and for months the pc was fine, no problems at all running the game at max settings, then about 3 or 4 weeks ago, i was playing WOW and the screen went black, i had to reboot the PC.
This happened on two or three occasions so i decided formatting the PC and putting on Windows 10, tried playing WOW this time and it worked for about 10 mins then the screen went black and i had to reboot again. Was playing another game i play Star Trek Online and was playing for about 25 mins or so this evening and it did the same thing, the computer went really quiet in comparison to its normal sound (ie fans whirring) there was also a burnt smell, so i rebooted and voila back it came, havent tried running any games since
