Stana is having issues with her old Compaq Presario freezing frequently. She tried cooling it, and it helped for awhile, but it's freezing again. She updated her drivers, and when that didn't work, she uninstalled them. Now she can't even boot into Windows because it says it failed to install an update, and it's trying to revert back.
Leo says it sounds like the drive is starting to fail. It may be a good idea to format the hard drive and reinstall windows. Compaq also has a hard drive test she can run. Reboot and press F8, then run hard drive diagnostics. And as a last resort, she'll need to buy a new hard drive.
