CPU error / boot failure (i7-4930K, ASUS P9X79-E WS).

I just installed my new system, and no action when I boot up. The CPU diagnostic LED lights up on my motherboard. I removed the Corsair H100i pump unit to see if there was actually contact with the CPU, which there was, no problem. I reapplied thermal paste and up it back on, but of course, still no go as I changed nothing.

The hardware in the system:
- ASUS P9X79-E WS
- Intel Core i7-4930K
- Corsair Dominator 32GB DDR3 (4x8GB)
- ASUS GeForce GTX 780 DirectCU II
- Creative Sound Blaster ZxR
- Corsair H100i
- Corsair HX1000

I was grounded while installing this and touch thie case and PSU throughout the installation, so I don't think I shorted anything.

The other diagnostic LEDs blink when I power the system on, as they should when things are working, so I'm guessing it's just the CPU. When I check for a connection between the pump and CPU I also took out the CPU to clean it of course, and to make absolutely sure that it was inserted correctly (it wouldn't fit otherwise, so naturally it was).

Any suggestions?

Remove everything except the PSU, board, processor, RAM, GPU and cooler. See if it boots. If it works then the fault is with one of the things you removed.

1. Your motherboard doesn't support this cpu out of the box. You need to update the bios first.

2. Check for any bent pins on the socket.
3. If nothing of that works try to boot with one RAM stick on the first slot.

Thank you to both of you. I first checked after disconnecting all the disks and the sound card, but still no go.

But updating BIOS via a USB stick did the trick, it now boots to BIOS. Just put everything back and it should be good to go

Did the motherboard beep during post? I am getting no response from my system and it's a custom loop so troubleshooting is a pita. I'm using a 4820k so I'm hoping a BIOS update will do the trick.
