How to unlock computer

Hello,
i inheated a computer form an uncle whom just passed away. i haven't played with it in 3 months. and now that i'm trying to get on it's asking for a password....which i have no idea what it could be. is there a way to over-ride this?

Where is the password prompt coming up? At start up, which is a bios password or at the windows login screen?

you forgot to tell us what password.
Is it a bios password or windows password?


For Windows Password, As far as I know , there are two main methods to solve the windows password problem as follows:

1st Method:
Start system and when you see Windows Welcome screen / Login screen, press ctrl+alt+del keys twice and it'll show Classic Login box. Now type \Administrator\ (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows.
Now you can reset your account password from \Control Panel - User Accounts\.
Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.

2th Method:
Windows password Recovery software:
for example:Windows Password Reset. It is easy and convenient to use.




For Bios Password, also two methods.

1st method . Open you computer box and Discharge to the Board manually

2st method . use BIOS/CMOS Password Recovery Tool
