My friend asked me to check out his PC, said the PSU is dead., i tested the PSU, it's fine. but there is no power getting to the M/B. Gigabyte GA-78LMT-USB3, seeing as the PSU works when using a shunt across the power/ground pins in the mobo connector i figured it must be the case/switch is the issue(?). so i am trying to figure out if the connectors on the F-Panel Header are configure properly. anyone any ideas?

thats what i was thinking., the 2 pairs of plugs are on the HD activity & Reset switch pins. (top left of block) , and the white/orange pair are in the bottom right corner, , there are actually three pins, only two wires in the plug. so i'm thinking if he has wired it up wrong, it could be very wrong, just trying to confirm for definite.

how can you tell which are the positive wires, and which are the negative ones. it seems like it should matter (?)

The motherboard graphics disable themselves if there is a graphics card installed. You can't get output from the motherboard if there's a graphics card in one of the PCIe slots.

What I described in the previous paragraph is the default behavior of the BIOS. If you manually change certain settings in the BIOS menus, you can get the motherboard output to work while a graphics card is installed.

Post a picture of the side panel off, maybe we can see something that isn't plugged in.
