Hey there, i bought a cheap Biostar K8M800 Micro AM2 motherboard for a computer i'm going to sell tommorow, but it doesnt work with the processor, an AMD Athlon X2 245. It does however work with an older CPU, an AMD Sempron. I don't know what is causing this, maybe the bios needs to be updated? The processor isn't compatible with this board? I'm not sure.. Thanks to anyone who can help me
