So i started having this problem on my PC a few days ago, i was playing a game and the screen just went a random color, Brown, at the time and froze, had to do a reboot, so i'll tell what's happening. My specs are

Core 2 Quad Q9400, 8 GB RAM and a R9 270x 2GB

The display starts flickering, and then it just locks up, sometimes the audio in the background keeps running then after a few seconds it also stops, and the PC reboots with black dots on the Blue Dell Logo, (sometimes i have to reboot it myself) so what may be the issue?
