My Computer has had insanely high physical memory usage the last week or two (as high as 99% usage). I would restart my computer and that would seem to help for a bit but it would continue to do this. I would try to close programs but they would never fully go away and in some cases instances of the same program would be open (stuff that should never have more than one open). I've disabled superfetch think it could be memory leak and it went down but only slightly. Has anyone had this problem or no what it could be?
