My desktop of 10+ years is possibly reaching its end. My BIOS battery died and I lost my Windows 7 key. And now Windows has changed their activation protocol and I can't get my version to reactivate. I use it only for movie watching. Since it is a Dell with surround sound built in to the motherboard and I have a system that works with the PC. Now I can't personalize it and the damn activation message pops up every 10 minutes which makes watching a movie hell. Does anyone have a working Dell with this type of setup their willing to sell?
