Hello all
My PC :
I5 3570k (my mistake to buy it because i didn't OC)
MSI B75A-G43
2x4GB G.Skill sniper 1600
MSI GTX 760 OC
Seasonic S12ii 520

Yesterday, everything worked normally
Today, i change stock CPU fan for Deepcool ice wind pro
It's the 1st time i do it, and my case is a bit tide, so I accidently broke 1 of 4 push pin of the hsf http://i.imgur.com/4zSbjQk.jpg
But 3 others is ok.
I connect all the pin from psu to the mobo and turn it on. But it start for about 10 sec, no signal on my monitor, and then restart. It keeps restart like this forever. I must turn off by killing the power.
I tried many methods, switch ram, clear cmos, disconnect everything only using chip + ram, but the same thing happen.
I tried to switch back to my chip stock fan but nothing change.

Is my mobo died? 🙁
And can i still use this deepcool hsf with only 3 of 4 push pin normally?
