Motherboard: ASUS M2N32-SLI Deluxe
PSU: Aspire ATX PSIV-600-2
(more hardware details in my profile)
Like the OP, the LED on the motherboard comes on, and the light for the ethernet plug also comes on when it's plugged in. But when I press the button to start the computer, absolutely nothing happens. Also, when I short out the green and black wires on the 12 pin connector, as per the instructions posted in the link in the OP, the fan does not come on.
Does this mean the PSU will likely be at fault, and are there any further tests I should do?
I have no-one to blame but myself, as I tried to move a desk the pc was sitting in, without first of all removing the pc from the desk. It worked fine before I moved it, but wouldn't work after. I have taken it apart and put it back together after closely inspecting all of the components, and there is no sign of any physical damage anywhere. I reckon the entire pc must have been rattled about a bit as the desk juddered over the carpet. I have also pulled the front of the case apart and inspected all the wiring, and there is no sign of any damage there either.
