Major mistake

Cheers for all of the suggestions guys, but nothing seems to be working. One thing I forgot to mention is the LED screen on the mobo doesn't light up At all.
 
This is on a 4930K? ouch!

I think it's going to be more likely to be the processor rather than the motherboard but without testing it's impossible to know for sure, looking at this overclock.net thread the recommended maximum on air was 1.2V, absolute max by Intel was 1.4V and that was for the more resilient SB-E so I presume IB-E limits would be lower.

Do you have any way of testing it? friends with X79 etc? then you could try RMAing to Intel and play dumb "it just died". :p
 
Come to the conclusion the CPU is dead, shame as it's under a month old. Also a pain because I sold my 3820 the other day so I can't even test that.
 
You should still get LEDs on the mobo even if the CPU is buggered though, i'd have thought... Problem/Dead/Faulty CPU i'd still expect power, but with a series of beeps from the mobo to indicate an issue.

Pretty sure i still got a boot last time a CPU failed on me, just got a lot of beeping from the mobo as a result. I guess behaviour may have changed with mobos since i last had a failed CPU, because i've had barely a CPU fail on me and the last one i can recall was a good 8+ years ago..
 
I honestly don't know how motherboards behave these days with problem/faulty CPUs to say with any certainty at all, it's been so long since i've encountered one(touch wood it stays that way).

I'd still suggest testing the motherboard outside the case with just the bare essentials, ie. literally break it down to the barebones and rule out a short potentially happening inside the case.

Did you try bridging the green wire to a black one on the 24 pin motherboard cable whilst it's plugged in to the motherboard?

Think we can rule the PSU out at this point if two other PSUs are producing the same results.

It's not to check the PSU, that's why I'm saying do it with the 24 pin cable still plugged in to the motherboard.

I have had to use this method numerous times to get my PC to boot after a bad overclock.

Doesn't your mobo have dual bios?

Hey, I've tried both bios and also bridged the 24 pin as spoffle suggested. Neither bios work and the system powers on but still no LED and the CPU light is stillred but it will continue running:mad::(
 
cpu led on means exactly that,its halting on cpu error

done full cmos clear? battery out for 30minutes then try?
 
I was just thinking, when I removed the battery would that have reset the bios to basic default one? If it did then is it refusing to start because the CPU isn't detected. Because the way x79 boards come ivy isn't supported.

no it just resets the current bios to default settings,it wont change the actual bios version
