I just purchased an Intel DX79SR MB and an Intel i7-3930K CPU and a Corsair AX750 Gold PS.

With 32G G.Skill Ares F3-1866C10Q RAM and a Aerocool case. All parts brand new.

When I assembled the parts there was no power getting to the board. I tried the PS in another PC and it appeared to be working ok. I then went to the Intel site which suggested I try the board outside of the case as there may be a short. It made no difference. I stopped testing on the assumption that if it was a short I was not going to take the chance of damaging the CPU by further testing. I sent the board back to the supplier who replaced it with a new board. I have since reassembled the parts but I am having the same problem.

I am now completely confused. I have removed all the RAM and tried to boot but no luck. All of the internal fans and CPU fan does not rotate.

Would a defective CPU cause this problem?
