Hi!

I have one (well... now almost 2) iMac's 2011 21,5". I bought the first one with windows running on it due to a faulty GPU.
So i decided to make it run like a charm and do some upgrades. Ive bought a WX4150 4GB and 32gb of compatible ram 1333 mhz, but in the first build i kindda broke a capacitor on my new GPU, got electrocuted and made the PSU smoke a little.

I ordered a new MOBO, GPU and PSU, put everything together carefully, but now only DX LED 1 lights up. I have another identical iMac that i bought trying to use the better looking case, so i have 3 mobos, 2 PSUs, and basically spare parts for everything else.

I know ill have to flash my GPU, but i dont know if my DX LED should only be 1 before this flash happens. Can someone help me please?
