My computer has been crashing mostly while playing Guild Wars 2 and Archeage. It will crash, go to a weird colored screen, and I have to manually shut it off. I did a memtest and everything checked out, and I also tried switching the power supply out with one that wasn't having any problems and that didn't work either. I've also tried playing the games on the lowest settings and it still doesn't really help. Any help would be appreciated.
