i think that your power supply has a drop voltage just replace for another

Green LED on PS means it's getting AC power. Orange light on motherboard means it's receiving power from PS but it may not be the correct voltage. The power supply isreceiving power from the source but is unable to properly distribute it to thecomponents. This can be caused by a defective power supply or a defectivemotherboard. Just to make sure that nothing else is causing the problem, removeany PCI cards like modem, video card, sound card, etc... Remove the memorymodules and disconnect cables to CD/DVD drives. Look at the USB ports to see ifany are damaged.

I am having the same issue, did you resolve yours?
