I play world of warcraft, and sometimes when I'm playing in full screen mode, i accidentally hit the windows key, which stops the game because the start bar has been initiated. Every time it does that, it either takes forever to ''catch up'' (meaning my desktop takes forever to ''load'') or what usually happens is my computer will all the sudden quickly shut off, and restart immediately. I really don't know the cause of this, my computer is custom build, but the mobo and processor are really outdated. Everything else is fairly new. Could the processor be the problem?
