your problem is that your mobo connectors to your case are connected wrong. Look at your manual and the LED, PWR LED, SPKR, HDD LED, RSET SWTCH configurations. you probably got a wire or two crossed. Try flipping them the other way if you've double checked and they are correct. The white side of each connector is always either the negative or positive. Its ALWAYS one of those, but at this point in time, I am afraid I cannot remember. Need sleep.
