The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased.

If you have forgot the BIOS password of your desktop computer, then you need a simple way to change your BIOS password. Its not that difficult because you just need a simple trick to reset your BIOS password.

* Shutdown your desktop computer and switch off the power to the CPU
* Open your CPU cabinet
* Find a circular, (mostly) silver metallic object on the motherboard. This is the CMOS battery
* Carefully remove the CMOS battery and leave it out for about 120 seconds. This will flush the CMOS memory which stores the BIOS password and all other configuration.



* Set the battery back into place and power on the computer.
* The computer should then warn you that the CMOS configuration could not be found. You can either reconfigure it yourself or restore defaults. Restoring the default configuration should be fine.
* You will notice that the BIOS password has been cleared and you can boot without it.

Note : Once you remove your battery from the mother board, you will find that all your time settings in your computer would be lost, and some softwares may stop working which are based on your computer time.

Good Luck...

There is a good chance that you could restore the computer without the restore discs. It all depends on if there is a recovery partition built into the machine. Here is what you should do:

1. Restart your computer.
2. Tap F11 a few times before the windows loading screen.
3. Choose to restore your computer if step 2 worked.

After that your computer should be like new.

If you don't have a recovery partition try contacting microsoft and see if they can give you a copy of the operating system you are running. Just make sure you have your product key handy. It should be located somewhere on the case. Good luck.

Remove your CMOS battery, OR Take OFF the jumper. Wait a bit, reinstall battery or Jumper. Restart should be all good. There is usually also a key that you can press at boot time to restore you BIOS to a default speed. Usually it is "INSERT". Try that first.

Remove cmos battery, clear cmos with jumper (Be aware to ensure no power cables plugged in to PC or it will damage mobo), re-insert and it will reboot.

Hi there.
If you don't have the option of hitting F12 to change the boot order to the CD/DVD just as the computer starts up then you will have to enter the bios to change the boot order.
Restart the machine and hit either Del or Esc to enter the bios, look for the boot order and set the CD/DVD as first boot device, hit F10 and exit the bios, the computer will restart and you should now be able to boot from the CD/DVD.
Please post back with the results and if you need anymore help.

Good luck and thanks for using FixYa!!

It sounds like a dead motherboard. Try removing the CMOS(BIOS) battery and replacing it. Then try removing and replacing the CPU as well. If you get the same result then you might be looking at replacing the motherboard.

Hi, You need to enter your CMOS/BIOS setup and set your "First Boot Device". Immediately after powering up, press the "Del" key, display will show CMOS/BIOS settings. Verify that all your hard disks are being detected/recognized by your PC. Thereafter, set your First boot device to your new HD. Save and Exit. Hope this be of some idea/help. Post back how things are or should you need additional information. Good luck and kind regards.
