My computer keeps randomly restarting itself, and its got to the point where it happens at least once a day. I turned it on a few minutes ago and got on the internet then it froze and started making this really high pitch noise, which didnt stop until i switched it off about 30 seconds after it started, in case it exploded!
Does anyone know whats wrong with it, and if it can be fixed? Or has it just had it?
Thanks for your help
