Dear MegaWorks:
Did you build this system yourself or is this a brand named manufactuered computer ?
If you built it yourself, please check to see that the wires coming from the power button (and other power functions) of the computer are on the CORRECT pin buttons located on the motherboard (get out the old instruction book for the motherboard and look at the diagram where it will show you the ORDER for the power wirings to go on the pins on the motherboard). Make sure you get ALL of the wirings on the correct pins and ALSO make sure they are on in the right direction, i.e. positive and negative pins oriented in the right direction. This can be very confusing to get these in the corrrect positions, I know I have to study them VERY closely every time I put a system together. Also, I think different motherboards have different skeems for the ordering of these connectors. Good Luck.
