hello I will test to explain this as excellent I can. My mother shut down on me last week, and it will not run on. I am acquiring power to the board because the red led is glowing. When I press the power supply key on the back of the unit when I press the button on the motherboard, what I do see when I turn it on, entire the leds on the board will flash on fast too the led in the power supply fan will flash and the fans will only kick and nothing. There is an 8 pin power attachment on the power supply and it is attached to the board. when i pull it off and press the key on the mother board the unit will work,but no power to the central processing unit. I tested another central processing unit and similar trouble. Does anyone have an answer for this trouble.
