What OS are you having? On xp you can try this: Boot computer and press Ctrl+Alt+Delete twice when you See Windows welcome screen / login screen. It'll show classic login box. Now type "Administrator" (without quotes) in username field and leave password field blank, press Enter and you should be able to login Windows. Now you can reset your account password from "Control Panel -> User Accounts". On win 7 or vista: Ctrl+Alt+Delete won't work, you have to use some windows password recovery Tool.

I know some methods to reset bios password. 1. The best and easiest method: Close OS and shut down the electricity power of computer. Open your computer box, take out the cmos battery from the mainboard. Then the bios password will be reset to blank. Put it back after a few minutes. So I would suggest you the 1st method. Hope it helps.
