I've been building computers for 20 years, but have never had this kind of a posting issue.

Just swapped motherboards, everything else is the same.

All plugged in, PSU on, mobo light showing it is receiving power.

Press the power switch, the PSU spins up, but no post, nothing at all from my machine. Open the side panel, try again, and I see for the briefest moment the fans twitch, but that's it, no beeps, no fans, nothing apart from the PSU spinning up and the mobo power light being on.

Tried without graphics card, swapped out the ram, cleared the BIOS using header, cleared the BIOS using battery. The same thing keeps happening.

Any ideas?
 
If you try without RAM do you get a beep from the mobo speaker? If not could be a duff board. I'd also check its all properly grounded at the standoffs and make sure you've not missed any AUX power connectors!
 
That's what's bugging me.

Everything is exactly as it was with my other mobo. CPU is brand new, PSU too, and both have been working fine for months.

Tested the new board with my spare cpu a while back, and it was fine, leading me to think all would work without a hitch :(

CPU Motherboard and memory compatible?
 
Well my back up is a Giga Z77, 2700k and Corsair RAM.

Some googling seems to show that the ASUS P8Z77-M Pro has loads of issues, dammit!

First time ever having ASUS and it is poop :/
 
Yeah, I think my new mobo has systemically killed 2 2700ks :mad:

Just put everything back together how it was, fans are spinning, but now there is weird intermittent buzzing noise coming from my machine.

It's not the HDDs, as I have disconnected them all, gfx too, it sounds like it is coming from the socket area, WTH?
 
Well my spare celeron is working fine, I can't tell if the other mobo has bent pins, they all look kinda normal.
 
Try to replace the RAM. A similar boot loop happened to me the other day, the pc would turn on for a few seconds and then lose power.
 
After much testing, the "better" mobo has indeed fried my 2700k.

Celeron is working fine in my original board, 2700k just makes the weird buzzing noise and doesn't post. Looking at the underside of the 2700k, one of the contacts looks discoloured, slight tinge of brown, like a scorch mark. The relative pin on the "better" mobo doesn't look in any way bent, but given my original 2700k died in the same mobo, I'm inclined to think it is the problem.

FFS, spend £60 on a mobo that reviewed much better than the one you have, and it takes out TWO £250 cpus!

I must have been lucky with the original Intel RMA, don't think it will go that way for me this time, as the mark is a dead giveaway.

And to add salt to the wound, the mobo only came with a 3 month warranty, which expired last week (as I have moving house, I never got around to switching out the mobos).

All in all, £300 down the toilet, yay!
 
Ha! Took a punt, and Intel honoured this RMA too! New 2700k on it's way to me.

Binning the stupid ASUS though, £60 cpu killer!
 
i wouldn't have thought the board could kill cpu's like that,good find

you might aswell go z77 motherboard now?

What did intel request in order to rma? I'm asking because I'm about to buy a new cpu off someone without the receipt
