I just recently finsihed building a computer (or so i thought). When i turned it on, it said that the CMOS Checksum is bad; it also says that the processor is of an unknown revision. A friend told me that means my processor is is incompatible with my MOBO, but when i check the MOBO, it says my processor is compatible. My processor is an AMD Athlon 64 Processor 3200+ Socket 939. Please help!
