First occt test said CPU too hot, so we went inside the computer and cleaned up lots of the dust. 2nd occt test was completed without error. \n\nNote: When computer was turned off to dust when it boot again no bsod's!\n\nThanks alot, any more suggestions? \n\nHow long did you run occt for? I normally let it run for a couple of hours. From what you've said you've been suffering from high temps due to dust. If you have anymore issues though don't hesitate in getting back to us.
