The clear CMOS jumper, is usually located near the round battery in your motherboard. Look for a jumper called JP1, as this is the one you need to alter.
I can't tell you exactly where it is on your board, as it differs from board to board.
The best thing to do, is to check your manual, or go to the motherboards manufacturers website, and download the manual from there if you get stuck. (Where the white pci slots are located on your board, it's usually found stamped in between the slots, it will say something like Asus A7v of similar, from here you can Google it.
If you don't happen to know your manufacturer, download a program called belarc advisor (its free), install and run this, and it will tell you everything you need to know about your pc.
Top right hand corner of the screen it tells you the boards manufacturer, and board number.
Hope this helps

The BIOS rest jumper is toggled by placing the jumper of the specific jumper pins. This causes the connection to close the circuit and trip the internal reset.
A jumper is a small metal and plastic device used to complete circuits on the motherboard by 'shorting' pins. The BIOS reset jumper is one example.

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.
if you don't know what the password is you will have to reset the bios by tripping a jumper or removing the watch battery on the motherboard.
The function of a bios battery is basically to reset your bios if something goes wrong and you corrupt it. Bios batteries usually contain a little bit of information on them. Therefore, when you remove a bios battery, it goes back to default settings. **Note** removing a bios battery is usually a last resort to reset your bios. There are several other ways to reset your bios such as a jumper cable or (included in some never motherboards,) a reset bios switch.
There are three ways to clear the CMOS on a computer. You can access the BIOS menu and reset the BIOS settings, you can use the motherboard jumper or clear it by reseating the CMOS battery.
Obviously, it doesn't have any, with the possible exception of a BIOS recovery / config jumper.
You need to find a jumper locked on the motherboard with the label "CMOS clear" or something like that. It will be useful for you to check the owner manual.
