How do I save my old computer?

I know it's old, but I come from the "Use it up, wear it out" kind of family and really want to rescue this piece of garbage. HP Support informed me it's too old and they no longer have the Recovery Disks for my Pavilion DV 9700. Any suggestions? I've a lot of experience with installing Windows XP from DOS prompt. Already reformatted this thing back to factory settings enough times to know the malware is too imbedded. I'd hate to have to take it out back and bury it next to our dog.
