My wife has this really old Toshiba Satellite laptop. She only uses it for email and Freecell, and an occasional Gogle search, so until recently, it was fine.
The battery has been dead for years, so we leave it plugged in and turned on. A couple of weeks ago, we turned it off while we were cleaning house, and ever since, it works right after a reboot, but very shortly after that it gets so slow that it is unusable. I ran a virus scan on the hard drive with Avast (the free version that always runs in the background). It came back negative. I did a defrag, and that didn't help. I would like to get it running again, but I'm out of ideas. Do you guys have any?
