I bought an AMD Phenom II X4 945 95w CPU for my Asus M2A-VM HDMI motherboard. I installed it fine, and it works perfectly. The only problem with it is it says "AMD Processor Model Unknown" on startup, I know this doesn't matter because the CPU works, but how can I fix this? I also forgot to clear my BIOS, as I'm not 100% sure on how to do this.
