I am experiencing a problem when I try to play Starcraft 2. I get past the login screen and within 15 seconds to 5 minutes, my screen pixelates. I can still move my mouse but it is very slow and "crawling" and kinda skips around through the pixelation. Only way to fix it is by restarting my computer from the reset button. I don't have this problem when I'm not attemptin to get on SC2, although I have been getting a lot of blue screens lately.
Any help is much appreciated! Trying to get my comp in order for Heart of the Swarm!
