Evening all,

Just rebuilt into X79, many hours later I'm at the point where I hit the power button, the machine will fire up for a half second or so (enough for LED's to come on and fans to twitch) and then off again.

What I've tried so far:

Jumping the PSU (green and black), PSU fires up fine
Removed all memory and tried one module at a time, same fault
Removed everything with the exception of one stick of memory, nothing.

Have been googling for a while and its getting exhausting, keep reading about the probability of the motherboard shorting against the case so I removed the motherboard enough to keep it away from the case and still nothing.

Really starting to scratch my head over this now so if anyone has any ideas or suggestions please share!

Motherboard is a Gigabyte X79-UD7 with a 3960X.

Thanks in advance chaps :)

SOLVED: TL;DR - CPU was a dud!!

It's Saturday night.:rolleyes:

More details please, what psu & wattage.

Remove motherboard from the case & rebuild system on the bench.

Also remove battery & clear settings, start afresh.

Is what I've just realised :rolleyes:

Starting to loose track of time!

Sorry, PSU is a Corsair HX1000, Just about to remove completely from system to bench test.

Edit: Fully bench testing is going to be a pain too, damn watercooling.

My guess is something is grounding out.. CPU mount back plate maybe? Have had same happen to me a couple of times. First time it drove me crazy... and I still am. :)
 
My guess atm as that sodding sticker the seller (had the sellers hologram logo on it i might add) put on was causing a short.
 
Interesting place to put a sticker.

Reminds me of the time when my Evo VIII MR would die temporarily every time I accelerated. It turned out that the air intake manufacturer had stuck a moisture absorbing sachet into the cone filter which kept making a seal when throttle was applied. Took me about a week of stripping out bits to find out the cause.
 
The bay, via reputable seller however, have sent them a message already, looks like the chips a dud, time to get my money back and go retail I suppose.
 
What would happen if I booted with no processor in? Would the PSU still flick over and power the fans etc...? As I really need to be 100% sure on the problem here.
 
Not looking good anyhow, with CPU in, hit power nothing now happens, remove CPU hit power the same happens.
 
Really? I've never had a dead motherboard and/or CPU before so I have absolutely no idea.

Any specific way of testing?
