restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer

Windows Advanced Options Menu

Please select an option:

Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt

Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)

Start Windows Normally
Reboot
Return to OS Choices Menu

Use the up and down arrow keys to move the highlight to your choice

Select safe mode with networking to download

type in net user username

For eg. If you want to change administrator password , type net user Administrator

it will prompt you to enter the new password

enter the new password and the password is changed

or for the bios password

Then type at the C:\> prompt: type

DEBUG

and hit Enter. You'll see a dash (-) at the DEBUG prompt. Now type:

o 70 2e

which will show as -o 70 2e at the DEBUG prompt. Hit Enter. Then type:

o 71 ff

and hit Enter. Finally type:

Q

and hit Enter one last time to quit DEBUG back to the C:\> prompt.
Now you're ready to reboot your PC, and press the appropriate key or key
combo (look it up in your motherboard manual if you don't know it) to access
your BIOS Setup.

Youll notice the password is gone.
