download and run this free software. http://www.microsoft.com/security/malwar鈥?/a> Also download and use http://www.download.com/Advanced-Windows鈥?/a> Use this to keep your pc running smooth. If your talking about reinstalling windows on your PC from scratch, the only way is to have a windows installation disc. Run the programs I sent and see if it'll straighten you up. You should be running a good virus protection at all times. If you don't have a virus protection download http://www.avast.com/eng/download-avast-鈥?/a> Also a great free program. Good luck.

You have to have a disk to get windows back after reformatting your hard drive.
you have to have an operating system to load when your done formatting the pc. if ur unfamilar with that type of stuff i would recommend AVG form downloads.com. Good luck
Some PCs have a hidden recovery partion on the hard drive that is accessed by pressing (usually) F11 immediatly after you turn on the PC. Check for yourself to see if this is the case.

Make sure that you backup what you want to save..These


instructions, will clean everything off of your hard drive, so you must back up anything that you want to save. I have done this three times, and I got these instructions, from a computer tech. When starting your computer, tap the F-10 key. click on next-yes-and follow the instructions, that come up on your screen. When you are finished, your computer, will look just like it did, when you first bought it.Do these steps, in order, when finished.


1. set up windows firewall


2. windows update (click express)


3. install your anti-virus program (update)


4. install anti-spyware (update)


This is called a ';system recovery';
