Brand new and burnt out FM1 board

Hi all, I recently bought an FM1 motherboard from technextday.co.uk.

I unpacked it, etc and set to work fixing it in my tower, I had no processor or RAM but wanted to check that the motherboard loads up so I fitted the I/O shield to the back and screwed the board to the case. (a guide I used mentioned a removable chassis inside the case, but I have no such plate in mine, I was a bit concerned at first that the actual case would cause a nasty short circuit against the back of the board, but noticed there were studs on the back so assumed it would give the relief needed of the solder and be fine). Anyway, I plugged all in and hit the power button. The LED lit up for a flash and died, and would not turn on again.

I then noticed the I/O Shield had bits of metal around where the socket holes had been cut out sticking everywhere so I took it out and just let the board lie where it would have been screwed in, and plugged the power cable back in and hit the power button, and the power supply whizzed, and the power LED lit up red (I assume because there was nothing plugged into the board)

Then after getting rid of the ragged edges of the I/O shield I fitted it back in and screwed the board back in, and it powered up fine, happy days thought I. So I held in the power switch and unplugged the power cable.
Oh no thought I when I smelt something burn!
If you've ever used a metal grinder, this is exactly what it was like!


I know I'm a flipping lunatic for fidgeting about with a board like this and I really am a danger to myself... not to mention the 30 quid thrown away (potentially!)

So is the board likely to be toast and absolutely useless or can it be resurrected.
I assume asking ASRock nicely for a replacement is off the cards, but I honestly don't know what might have caused this. It powered up fine using the same setup without the I/O shield.

Any ideas or advice?

Many thanks
