Z77X-D3H rev 1.1 not post fans start/stop spin

Z77X-D3H rev 1.1 not boot with videocard

Specs (first is main)
CPU: i5-3550 or i5-3570k
RAM: Samsung 1600 2x4Gb or Hynix 1333 2x4Gb (tried to use only one module and change slots)
GPU: Gigabyte GTX 650TI 1Gb or Asus EN9800GT
PSU: Seasonic 750W (SS-750??) or FSP 500W (2x4pinCPU, 6Pin Video) or Zalman 460W (460B-APS)
HDD/ODD: all sata 1-2xHDD or SSD + 1xODD


Problem:
Everything was working only first time, before we turn off PSU.
Then it is not boot (fans start/stop spin for 1 sec) with any of this cards. (first time all video cards was working)

Tried to:
Switch Gen3 -> Gen2 -> Gen1
Set boot priority (PEG) and disable igpu
"Clear CMOS" (pins, remove battery)
update BIOS F15 -> F16 ->F17f -> F17h -> F17i
checked socket pins
switch/replace ddr3 modules and cpu
boot without usb/sata devices (only ps/2 or usb 2.0 keyboard)

Result:
All the time cpu and videocard fans start spins for 1 sec and stop, power button not work any more (had to use switch on PSU on/off)
If remove video card - PC boots.
When 6pin disconnected from 650ti - PC boots but discrete card not work, only iGPU.

Check all hardware on other mobo -> everything working.
All hardware is new, except:
650Ti is 2 month and 9800Gt is few years, New HIS HD7870 form that PC comes next week.

Multimeter shows (on 6Pin and Molex) 12,3V on system boot and on other PC(with videocard) it drops to 12v on full load.
Cant get real value on Z77X-D3H - start/stop to fast - my multimeter shows only current values, not max


Any ideas what to do?
I can hold this mobo for a couple of days.

did you clear the cmos by removing the motherboard battery? tried without the graphic card and use onboard graphics?

use onboard igpu and look in the bios,set first initial display as peg or pci-e,save/exit then install your graphic card and connect monitor to it and see if you get anything on the display

yes, i try all of that

Set boot priority (PEG) and disable igpu

one way is boot PC with videocard in PCIex slot (x16 or x8 or x4) is

When 6pin disconnected from 650ti - PC boots but discrete card not work, only iGPU.

you've tried the latest beta bios??

Z77XD3H.17i.zip f17i ??

Tried to:
update BIOS F15 -> F16 ->F17f -> F17h -> F17i

every time after bios update -> "load optimized default" -> save and exit -> turn off PC -> insert video card -> no boot -> clear cmos by pin-> no boot -> remove video card or 6 pin vga power -> PC boots.

also i tried remove battery for 5 min

please, read post #1

do you have your 7850 yet? tried with that? if it doesn't work with that card then I would rma your motherboard as it could be faulty

it might be a faulty pci/pcie switch on the mb,im not 100% sure on that but have read that it can fail

Nope, still waiting, HD7870 should come tomorrow(26 feb).

I tried to disable all periphery/controllers - but it didnt help.

So there some switch between PCIex16/PCIEex8 and CPU??

yeah I thinkso,there a switch that detects what slot your graphic card is in,could be faulty

Be curious to see if it works ok with the ATI card. A lot of the problems I see like this are with Nvidia cards.
Let us know how the new card works......

HIS HD 7870 -> everything start without any problem

Replace HD7870 with my 650Ti -> still working ... 0_o

Tried several times on table. Then put everything in case.
We have previously tried to disconnect everything and leave the motherboard for a while, but it didn't help.

I don't know what it was, I hope it will work in the future.
He took case home to install os and etc.

Btw, mobo POST(from power up to bios logo with only ps/2 keyboard) in ~7 sec (~6 sec with fast boot), my asrock ~5 sec.
Imho, my z77x-d3h rev 1.0 was faster, at least 5 sec too.
