So sometimes when I play Planetside 2, instead of the usual crashes for that game, the computer becomes completely unresponsive and the last few tenths of a second of whatever sound was playing last will repeat over and over. The one I just had now was worse, the computer rebooted itself and I caught a glimpse of a blue screen but all the text I could catch was "in order to prevent damage". What's super scary is the fact that a graphical glitch carried over into the new boot and didn't go away until Win7 booted up. A grid of white dots was on the screen, on top of the usual stuff the BIOS displays on start up.
So far this has only happened once outside of a game. Despite the fact that I just put in three brand new memory modules, I really hope it's not their fault.
