Re: weird problem
Before you reinstall everything try Windows restore and go back up to before you played around, if its you main system files that are missing try putting your system disc in and running a windows repair, when you get your system right and clean make a back up of your system before you start meddling then if you do make a mistake then you can restore to your previous good working state.
