your best bet is going to be reset the bios to defaults. your motherboard manual will tell you how to do this, should be listed as "clear cmos." or you can remove your bios battery, unplug your computer from the wall outlet and push your power button a few times, doing this will also reset your password.
Well I cleared the CMOS and now the computer wont boot up. And yes I cleared it when everything was off. Whats going on??
