Thread moved; to a board where you're more likely to get the best coverage..

Personally.. I wouldn't worry about uninstalling Windows if it's really playing up - Windows is only a program. Back up all of your data, of course; in a safe place, and virus scan or selectively bring back your data if you think it might be affected with something..

You have nothing to lose if you back everything up, except a cost in time of setting everything back up again.. That said, wait until / if someone responds who knows more about your specific problem..
