Dear Experts, I have an older HP Windows Vista computer that a friend of mine wasn't using and gave to me a few months ago. Everything works okay, except that the hard drive on it is constantly cranking away on something, all day all night. I look at the processes running and don't see what it could be that's running in the background so much. It's starting to drive me bonkers frankly - all that clattering. Is this a Windows Vista thing? If so, no wonder nobody liked that OS. Can whatever background process it is, be safely stopped?
