Major mistake

Today I tried a different CPU and I had the same result. Is there any chance it could be something simple like corrupt bios?
 
could be but to find out it would cost a tenner for a bios chip,they pull out

if not then has to be the board itself?
 
Guess so, the day It all messed up I don't think I mentioned that I was able to boot up after for a short time. Inbetween this 2 digit led screen on mobo showed 00 which means no CPU detected I thinks then restarted and could access bios again. Then I think I removed The bios battery and I've had problems ever since
 
could be badly corrupted bios

doesn't that board let you flash the bios without cpu working? using usb stick,if so try reflashing the bios and it might recover it
 
The only thing confusing me though is the mobo screen being blank, that could possibly be bios fail or so I'm hoping.
 
Maybe you blew the actual northbridge (X79) chipset on the motherboard? from what I've briefly read the VTTD supplies PCI-E voltage on the CPU but it might feed through to the chipset as well?

Hmm okay, why did you think a bios flash would help then if it does it on other boards? I thought with you trying a bios flash it meant that you had the CPU working.

Ran out of ideas i guess, not sure what i should do now though could try the RMA mobo i guess but cant see anything happening. If not then ill just buy a complete new one. Thing is, when i used the x79 ud3 it wasnt flashed anyway but dont see why it would turn itself off also

Is the X79-UD3 yours? if so if you want you can send it me and I'll test it and flash the latest BIOS for you (I have a spare 3820+mobo), you'll have to pay return postage mind.

Or if you want to send me the 4930K I can test that and then forward it on to Intel or wherever you're RMAing it to if need be. I'd offer to send you my 3820 but I don't want it being used in a potentially dodgy motherboard. :p
