I left my computer on last night. Came down stairs opened up diablo 3 and noticed little like bad pixels like small spots with wrong colored pixels. Then when i went into the game stuff was just all weird like models were huge and all over. so i shutdown restarted and basically the same thing happened. So i restarted again went into bios check temps and they weren't to high but just for fun i turned my CPU clock speed back to default. and now everything appears to be ok. So ugh?????????? What do you think caused it?
