Dell xps 400 windows xp

I'm having issues with my computer when I boot it up it gives me 2 options hit f2 or f12 when I do hit the button they don't go to them and I KNOW my keyboard works perfectly fine but that's not the problem. The problem is there is a system password which I don't know what is and when I TRY to type a password in, it does not want to type ANYTHING in... Does any1 have solution to my problem? Please help me thanks!
