please guys...............

before you start up try to get into recovery mode and then do a factory restore you'll lose everything but thats the only thing i can think of. I had to do this to my computer also

how do i do that ???????

LOL just noticed we have the some computer but to do it while you computer is turning on press ctrl+F10 and that should do it mine just went into it by itself but not sure for you hope this helps

Nope still wont work ;~(

To enter into the Recovery Console you have two options:
1.) Reboot the computer and before the Windows Logo screen appears tap F8. If you're lucky, you'll have the option to boot into Recovery Console.
2.) If you're not lucky enough to have the option to boot into Recovery Console via step one, find your Windows XP CD and boot from it. Once it loads the files it'll ask what you want to do. You're going to select the "R" option to repair the pc via Recovery Console.

Once you get into the Recovery Console it'll ask which Windows install you want to use. If you're a regular computer user there should only be 1 listed (Usually listed as 1. C:\windows ) if you're a more "advanced" user there might be more listed. It is assumed you should then know which one to boot into if you know how to setup a multi-boot system.

After selecting the Windows installation you would like to boot by pressing the respective number you will be asked for the Administrator's password. It's time to enter it.
Please note:

There is a built-in Administrator account when you install Windows 2000 or Windows XP. When entering the recovery console that is the password the recovery console is asking for. It is not asking for the account you created during install or the one that you generally login to. Unless, of course, you're logging into the built-in administrator's account which is not a good idea. If the password was/is blank then you shouldn't get a prompt asking for a password. It'll just load into a C:\> prompt. However, if it asks for a password and you don't remember setting one then there is a known issue with OEM versions of Windows XP and Sysprep (don't worry about sysprep, for another time) with administrator's passwords. If that's the case, then just visit this [ Register or Signin to view external links. ] website to download and use updated Windows XP Setup Floppies for your version of Windows XP. If by chance you have forgotten the password, I'm sorry, we can't help you recover it. You can, however, read option 3 or 4 for a way to repair your computer.

sounds really good and is helpful but i dont have the disk..........

what do you mean, every computer bought from an Authorized dealer such as best buy needs to have all installation disks, try looking for them if that's what you mean.
