Also for drivers, if you don't have the CD's that came with the computer, go to the manufacturer website like previously stated, there should be an option somewhere on the page for the model of computer you have for you to download the original drivers. 2 things about this, if you've upgraded any components of the computer the original drivers wont help, also the original drivers will most likely be out of date, they should have updated drivers on the page as well. I'd give you the links and things for the pages I'm talking about, but I don't know the HP sites that well. If you had a Gateway I could give you everything you need, I'm a Gateway whore here at work. Hope it helps
