def get rid of any oc'ing programs... when you push your comp past the limits of the program they start to freak on you. i've got 'core cell' for overclocking and it always pops open to let me know my frequency is fluctuating between say 2.4 and 2.399. thanks but i dont really give a rats ace, ya know? i'd rather just keep playing my game. i gotta remember to uninstall it...
