Jim has a Windows 7 computer and about two months ago it started messing up his mouse, which freezes up anywhere from a few seconds up to 5 minutes. It usually happens after checking his email and then going online for a while. Then he exits out and the mouse freezes and he has to reboot. Leo says that there's probably something running in the background that's slowing down his computer and causing processes to back up. Leo suggests trying another browser, like Google Chrome. What's likely happening here is that over time, Jim's computer is suffering from "bit rot" and there's something slowing it down. Once a year, it's always a good idea to backup the data, wipe the hard drive, and reinstall Windows, updating it to the latest build. Time for some spring cleaning.
That will also help clean up his hard drive to keep it healthy. Stalling out like this is a sign that the drive needs attention.
