Hello all, for a while now my games will freeze for around 10 seconds, repeating the same noise slowly, and then for around 5/10 seconds the noise will go REALLY fast, and then suddenly my screen flashes white for a second and then the sound resets and everythings back to normal again, this happens at totally random times and it seems to mainly happen in Counter Strike, so if anyone can help me out or tell me what it is i'll be hugely grateful, Many Thanks for the help
