Can't restore factory settings and computer running very slow.
My laptop recently starting running incredibly slow. It takes about 10 minutes before I am prompted to log on and another 5 minutes before the log on is complete. Once logged on the computer barely works. Most programs won't open and if they do they keep freezng and evenually shut down. I have anti-virus installed but when I try to run a scan Norton opens the scan window and it says the scan is running but never actually scans anything, even when the laptop is in Safe Mode.
