Hope this helps.

If you have forgotten it the only solution is to reset CMOS.

Hello,
If you dont know the system password for your System, forgotten it, or its not accepting it again, then you might have to reset your CMOS.
Which means you will have to unscrew your system, remove all cables supplying power to the board, locate the CMOS battery and remove it for a few seconds, then replace it and screw your system back.
This will reset your system's CMOS back to its Factory default settings.
(If you cant unscrew your PC yourself, you can just get a good technician to do it for you instead.)
Hope it helps.
Goodluck!

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 of the manufacturer 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 center pin to left pin, then remove it and join 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.
