I never had it crash but i did have a problem with CD's failing to burn in the last stages of a burn. I finally found out it was the folding at home program that was causing the problem. Shutting off FAH resulted in good burns. Of course when i am burning cd's or DVD's i do nothing else on that computer. Maybe just my quirk but i have never burned a bad CD(dvd) yet in years. It is my priviledge to have enough computers around that i can just use another computer to go surfing or do other stuff on.
