|Password for what ?|
For your own Windows user ?
Or - is it a password that was set in the bios Setup....
- a system access password - you must type it to use the computer at all ?
- a hard drive access password - you can get into the bios while booting but you must supply a password to access the hard drive ?
- a bios access password - you must type it to enter the bios Setup ?
A bios access password can be forgotten if you seldom enter the bios, but it's unlikely you would forget those other passwords since you would need to supply them every time you used the computer.
