well she does just use it for web browsing, she did alot of music downloading but hasnt recently but the music is still on the HD. It will just restart randomly while running an app. or just idleing. It has been doing it for months now but has move from once every few days to a few times a day. Im not sure of the temps, its more of a budget pc. but if it helps the exhaust fan is blowing cool air. I am a beginner with built pc's so im not sure about these things. Thanks
