I have this old pc the MB is Asrock K7VT4A Pro.
2 days ago every time i start the pc it get's to windows and it asks me for a password ( it never had one), i tried to go to cmos so i can configure so it starts by reading the cd rom and now it also asks for a password, i tried to reset the cmos, with and without battery  and nothing it still asks for password.Any ideas to repais this?  

sounds to me like something got into this machine and has messed with the accounts..

Are you saying it asks for a password and you can not get in, or are you saying it asks for a password and and you can bypass it like a nag?

If you really need a password to get into Windows and you never set that up or made any account changes then you have a nasty critter on that system
