Here is a little bit more help:
=================================================================================================
Hold F10 at start up. When the recovery screen starts. Choose Advanced>Destructive Recovery>Follow the on screen prompts. Choosing Destructive Recovery will return your computer to factory specifications. What you did previously sounds like you did a repair of Windows which allows you to keep other files and, programs on your computer. Returning it to factory specifications will remove everything except what originally came with the computer. The recovery will take about an hour. Then go to Microsoft and, download all of the latest updates for your computer. This could take several more hours and, could require several restarts. After you have all the latest updates. Reinstall your anti-virus and, any other programs you want or, need. Avast, AVG or, Avira are free if you do not already have an anti-virus. Be sure to save any photos, music, or other files you want to keep to CD or, DVD before starting Destructive Recovery. Creating a restore point on your computer will go a long way in preventing you from having to do a destructive recover in the future. Once the Destructive Recovery is completed. Go to Start>All Programs>Accessories>System Tools>System Restore>Create a restore point>Next>Name the Restore point todays date>Create>Close. You should create a restore point about once a month. If in the future you need to restore your computer you can simply use any of the previous restore points. Start>All Programs>Accessories>System tools>System Restore>Restore My Computer to Previous Date>Choose Previous Restore Point>Next>Next.
