I've had this problem ever since I first got the laptop, which is now about 4 months old and without warranty. While watching any kind of video, sometimes the computer freezes and creates a buzzing noise that comes from the speakers/headphones. The buzzing noise does not come from the fan. The freezing also occurs while I'm doing easy tasks, such as writing in a paper document. ALSO, the buzzing noise doesn't last very long, only about 5 seconds and then I would have to reset the computer using the power button. My computer has an A8-5550 processor and 8 gig ram. (not sure on graphics card)
Any help would be greatly appreciated!
