I have a AMD2200+ with the same motherboard. What updates are talking about? Is it a bios update or driver update? You should never update the Bios unless it is the completely the last resort to a problem.
You should check to see if the motherbaord is set at jumper free mode which will mean it will pick the CPU speed from default depending on the chip inserted. Can you let me know what else you did and I can try and help some more?
