I built my own PC for the first time. After I put all the components together, everything worked fine when I turned it on. However, I got unknown model for the AMD 6000 processor in the BIOS, Vista Welcome screen and Device manager. I upgraded the BIOS to the latest version, restarted the computer, and now the BIOS says AMD 6000, the welcome screen says AMD 6000. But the Device manager still says unknown model. Please, help. I looked for the drivers on amd website, the latest one is dated September 2007, but it is not for Vista.
