I just installed a new k8m800-m7a motherboard. After installing it the computer ran fine. After the first shut down it has no power to the fans, hard drive or keyboard. I have replaced the psuand the power switch. I also used a different power cord. I cleared the cmos to see if that would help but nothing. The board seems to be getting power at least when i plug in the internet the light comes on. Can anyone give me some advice of something I am overlooking.
