Now you can reset your account password from Control Panel - User Accounts.
Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.

Passwords. Those ubiquitious alpha-numeric codes that protect us and give us access to everything digital. Unfortunately, passwords can be confusing because, though your computer likely won't forget a password, you very well might. When this happens, you can be locked out from your whole system, as in the case of the Windows XP Administrator Password. This article will show you how to remove an Administrator password.

Instructions:

1. Insert your Windows XP CD into your CD drive and boot your computer. If you receive the message "press any key to boot from CD," press any key.
   
2. Step 2 Press Enter to setup Windows. After accepting the license agreement, you wil be asked if you want start a Repair process.
   
3. Step 3 Press R to begin the Repair process. Setup will now check your disks and then start copying files, which can take several minutes. After this, reboot. Let the computer boot normally (do not press a key to boot from CD).
   
4. Step 4 Keep your eye on the lower left hand side of the screen. When you see the Installing Devices progress bar, press SHIFT + F10. This will open a command line console.
   
5. Step 5 Type NUSRMGR.CPL at the prompt and press Enter. This will give you access to User Accounts. Remove or change your password. Write it down! After the repair is finished, you will be able to log on with your new password.
   

Good luck!

Seems data corruption on critical files. Download my upload HDD Regenerator v1.51.iso (less than 2MB), burn onto CD (as image, not as data!). Boot from this CD and scan the whole Hard drive to recover any data corupption (may take nights!). You may need to change to Boot from CD first in BIOS.
Good Luck!

If you have the vista disk, then just put it into the drive, and reboot. You may need to change bios boot order, which can be done by pressing f8 as the computer starts up, and selecting the dvd drive. If this does not work, then please refer to your user manual for the correct key to press. If you can boot, then the installation is self explanatory. Give it you country and keyboard layout, and then when the screen shows "install vista" button, undeneath it is a repair vista button link. Click this, and select your existing installation. From there it may ask you about "system restore" press cancel, and then hopefully, it will restore.  Hope this helps.

What do you get when you turn it on? What screen or message do you see?
