I have been experiencing some freeze problems lately, actually in the past 2 weeks. I have had a total of 3 freezes, 2 were freezes where the screen either went completely white or a blue-ish color. The third freeze was when I was browsing through YouTube and it just randomly froze, I could see the screen and everything I was doing, but I couldn't move my mouse or do anything. I'm not entirely sure what is causing this so maybe you guys know? Any suggestions?
