Hello. I'm having this problem whit my windows 7 (even after reinstalling it ) When i'm using my windows 7 at anywhere it somedays starts freezing and sound starts slowing and giving Buzz sound. When i move mouse or presskeyboard it freezes like 0.5 sec and after that it's again ''normal'' untill i move/press again. I have noticed that my HDD goes NUTS whit reading if i move mouse alot or press buttons alot. Could it be HDD failure or it's in my windows 7? Error log wont help you much because it's finnish. This bug happens pure random somedays i play over 6h whitout it but sometimes it can happen after booting computer. It's pure luck if it comes or not. More details will be explained if needed.
