No day in which you learn something is a complete loss.

First of all, you have to know that any attempt to reset the password is an advanced and complex issue for newbies and if you don't know what you are doing you should consult with an expert.

If you're not a newbie (or very brave) you can use 2 methods.

1. Physically reset the password.

Your BIOS resides on your motherboard which is fed electricity from a small battery. Disconnect your computer from power and all devices, remove the cover and try to find the motherboard battery. Remove it and then replace it again after a few seconds. On some models there are some jumpers you can move to restore default values to the BIOS, try to find relevant information by searching for your BIOS make and model online.

2. Using a utility. This may be risky and may cause unrecoverable damage to your computer. There are some utilities that flash the BIOS with an update and other that attempt cracking the password.

Here is an article explaining all methods and pointing out some utilities: http://www.dewassoc.com/support/bios/bios_password.htm

A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

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.

 

B. By Using Software:


I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds
