This was my sisters from work - she said she has no idea what happened or when for sure. I turn it on and it has the Compaq screen, goes straight to black with operating system not found. It has/had Win XP Pro, I have the Prod. Key but no disc's or recovery discs. Can anyone help with how to restore or where to get the discs needed to bring it back up. I want to give it to a home-bound person and I have no idea how. Thank You -
