I had a problem with an external powered USB hub yesterday - its power supply was faulty so I replaced it. When I reconnected it , to a USB/Firewire adapter in my Asus P8Z68-VLX motherboard, it still wasn't recognised, so I was fumbling around trying to connect it to the other USB port on the adapter and I felt one of the metal expansion port covers fall out of place, into the PC casing. The machine immediately lost power.
At first I assumed that the power supply had blown, but I've just removed the 24-pin connector from the motherboard, shorted the green/black pins with a paper clip, and re-connected the power. The SATA devices all seemed to power up - suggesting that the power supply is OK?
So now I need to know if my mother board is irreparably damaged (presumably by a short circuit when the expansion port cover fell into the PC case). Can anyone tell me how I can check whether my motherboard is dead?
