Asus p4p800-vm motherboard

Hi, when i started up my computer it went to post and asked me for a password,as i dont have one i pressed enter a few times and the computer is now locked. When i press the power button the fans run and the red light in the power switch stays on permanantly, there are no beeps from the buzzer, ive left the cmos battery out and the jumper moved,it takes 3 days to clear the cmos, the only problem is that the cycle happens all over again. I cant find out how to get to the bios to recover it or to clear the password. Does anyone know what i can do to fix this problem. Thank you.

I use the "del" key on the lower right side of the keyboard. You may have a section for the password. If you find it, press enter and leave a blank space where it asks for it, and press enter again to reset it. Then save and exit. Some oem boards have a special jumper on the motherboard you can move to reset the password. I'm trying to download the manual, but it's too slow; will have to retry later.

thank you for the reply, i have moved the jumper to clear the bios but it takes 3 days left on before it will clear enough to go to post, then the same thing happens again and locks the computer. im beginning to think the bios is corrupted or the mother board has a fault, i have read the manual and there is a crash free bios, ive downloaded it to floppy but i cant get the computer to run long enough to access it.
