If it's a desktop PC, erasing the cmos memory will usually clear it. Turn the power off, remove the cover. There should be a battery, these days they use a large silver disc watch battery type. Near it should be three pins with a linker on two of them. Move it to the other side, so the middle pin is linked to the other pin. Leave it there for a few seconds and then put it back in it's original position. Replace the covers and boot up. You will then have to reset your BIOS options etc.. On Laptops, they all most always write the password to EEROM or flash memory, which don't need a battery. Unfortunately, sometimes the only way to clear these, is to remove the chip and use a programmer to load it with the latest BIOS from the manufacturer or replace it with a new one. Dell computers have a master password which is unique to each computer. That password can be obtained from Dell customer service.

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand.
You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most manufacturers label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins the center pin to the left pin, then remove it and join the center pin to right pin.
Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.

How do you rest the BIOS password?
To reset the bios password you can contact the manufacturer and request the bios master password for your laptop or computer. On the motherboard there is usually a reset jumper or contacts. This will put the BIOS into factory settings and reset the clock. You will need to get the technical data for your motherboard to find out where this jumper is. On a desk top computer it will be a jumper that shorts two pins and is stowed in a normal , running, position. Move it across for a few seconds then return to normal position. On laptops, it will be a pair of gold contacts on the board, that need shorting with a wire or tweezers. I have ususlly found them under the memory modules.
