I would pull the drive and connect it to another computer or an external USB connection to back up your data. I have a Vantec BlacX Dock for this. Once your data is safe, replace whatever parts you want, and your Windows 7 license can be transferred to it. Considering it was an OEM system, I'd go for a new case as well. You can reuse a lot of the HP's parts, but finding a replacement board that fits will be either tough or costly. That's one of the many reasons that most of us build our own towers.
