I have a pc from my office (my own business) with XP. I had the pc on a network. The IT guy I hired to install the system setup an administrator password for the computer but i don't know what it is. I am now trying to give this pc to my kids and set it up, but can't do much without the administator password. I assume you can't change it, but is there a way I can wipe it out. To make matters worse, the pc I have doens't have a cd rom drive and when I plug in an external drive the bios doesn't see it. Can someone help here?
