Dang, oh well, I guess I'll have to get some Install disks, I was hoping to avoid that, thanks anyways!
Why do you need the disks? If you are re-installing Windows, you can check and see if there is a recovery partition already on the computer. That will usually install the drivers you need as well.
If you just need the drivers, as STARS said, you can simply go onto the HP website and get all the drivers you need.
