GIGABYTE mobo not working

[STRIKE-F]

So this is what happened.
I was playimg sc2 on my APU rig,withA10-6800K and GA-F2A75M-HD2
Suddenly the computer reset itself and the cpu fan starts to run at max speed.Nothing on display
I turn off the computer and restart it but same.Max fan speed and screen pure black
I took out CMOS battery,disconnect 220v power cable and left it while I had breakfast.Put it back,turned it on,nothing changed.
Disconnected 220v and shorted CMOS clear jumper for 10sec,nothing happened.
Tried hotwiring the main bios chip in order to force backup bios to rewrite it.Worked before but not this time.

I desperately need your help.What can I do???
RMA is my last option as I need it fixed pretty quick and it is sunday now..

Not sure exactly, best case scenario, it's just a problem with one of your cables. Worst case scenario, you fried something important.

what happened to me...

Booting machine, black screen, all fans going max speed - would not boot to bios or anything. Tried cmos reset, complete rebuild + minimum hardware, paperclip short for 2nd BIOS - nothing worked.

Took it to a pro (shop) for 2nd opinion - Mobo Fried

This sounds very similar to the problem that STRIKE-F started. You may have fried you motherboard STRIKE. It might be time to look at a new motherboard, or a new system depending on what you are willing to do
