Upgrading an old Compaq...

Thanks...but compaq's site didn't have the drivers If anyone knows where I could fine them, the computer is a Compaq Presario 9548.

And about the processor...I can't get the HS off, as it's glued on very well. Then, there is a sticker on the bottom. It must be made of metal, because it seems there's no way to get it off... Oh well, I think it's working fine, even if it's overclocked...
