    I have an old Compaq Presario MV540 that I use just for games. It's running on Windows XP.
    I had two user accounts on the computer that were password protected. Somehow, my lovely brother figured out my password and got into my account. He then changed my password along with his password. Then he forgot both of them (what a genius). We tried unsuccessfully to figure out the passwords for sometime. When that didn't work, he kept pressing random buttons (he just keeps getting smarter) and somehow, he set a COMPUTER password. So when we turn on the computer, it won't even go to the account page now. It has a black screen and asks us to type in a "Computer password" which he doesn't know. I'd like to get this ordeal over with and just reset the whole computer (nothing on there is worth saving anyway). We don't have any recovery CDs or the Windows XP CDs anymore as we had thrown them out when we got a Mac for general usage.
    How can we resolve this? Can I do anything without a recovery CD? Any help would be appreciated. Thank you!
