Boot the computer up in Safe Mode (pressing F8 on startup). Once the drivers and system files load, there should be two login choices, Administrator, and the one you created. By default, the Administrator profile should have a blank password.
Log into the Administrator account. Once your in, go into the Control Panel>User Accounts, and remove the password for the account you created. Once your done, reboot and let it startup normally. Click your profile and it should log you right on. You can then go back into the User Accounts options and then create a password for yourself again.
