GA 890fxa ud7 will not boot

[zinchead]

This is my second GA 890fxa ud7 board. I was not sure about the motherboard, so I rma'd it and the G skill memory.
I have rebuilt the new configuration as below:
GA 890fxa ud7 rev 2
AMD Phenom II x6 1090T
4 gig g skill F3 12800 cl7 memory   ( in the 2 white slots)
Noctua NH-D14 cooler ( i was a bit worried about the plastic spacers supplied)
2 x 3870x2 cards in crossfire
intel 160 gig ssd
coolmaster haf X case and coolmaster bronze 1000watt power supply.
All went smoothly with default bios. I never play around with bios settings until I am up and running.
Windows 7 x64 bit  installed in record time. I ran the computer for a full day.
I installed latest ATi crossfire drivers, and computer has not booted since. I can't even get to the bios screen.
I changed my power supply, but still no success.
The fact that it won't boot at all suggest hardware. I tried one video card. It made no difference.

Has anyone else had similar problems?

Are you getting any POST beeps when you BOOT? If yes, what are they?

Have you tried to re-set CMOS? See here if not sure how to do this: http://forum.giga-byte.co.uk/index.php/topic,2286.0.html

From your run down of the problem it seems that the Xfire drivers weren't compatible or corrupt. I agree with absic reset your CMOS and try with just one card. Failing that try removing everything from the motherboard and see if you get any response.

I tried cmos reset.
Makes no difference.

The cmos does not get a chance to deliver the bleeps.

the error code displayed on the board is no  88.

the embarassing thing for me is that I rma'd my last MB and memory for exactly the same reason.
New board and new memory, and the same problem.

Weird problem.

[zinchead]

Ok, I removed all cards, and even disconnected ssd.
No bleeps and still error code 88.
Later I will do a rebuilt and put on the standard amd cooler.
i'll keep you all posted.

Try just the PSU withoput anything except a fan as load. If you don't know how to do it you just disconect the motherboard connector and short out the GREEN and any BLACK wire on the PSU cable connector. If it is ok it will start and the fan will run.

[zinchead]

Just tried it.
Fan runs OK.
I'll do a system re built and check all again.

cheers

Make sure that the motherboard isn't shorting to ground somewhere(extra post etc). Try just adding one component at a time and checking as you go. Let us know how you get on. Good luck.

one small piece of difference is that the amd cooler has a 4 pin connector.

The noctua nh-14 only has 3 pin connectors.
What is the extra pin for?

[oggmonster]

Think the extra pin is for automatic fan control

well, there goes another interesting evening.
Rebuilt the whole machine and still no boot up.

My question is how a new built can work perfectly for a whole day, and over night not even boot up again.
This is the same issue I had with the previous M Board, installs Ok. Next day no boot. No hardware changes in either machine overnight.

It must be a vampire bite.

I'll leave it for a day to get my head round it.

Thanks for listening.

I think your problem lies in the memory. G.Skill says "Unfortunately not all AMD CPU/motherboards will be capable of DDR3-1600 CL7. This is why the memory is for Intel platforms, but as you know, as long as it is set to CL8, it will work just fine as well".
Unfortunately not all AMD systems are capable DDR3-1600 CL7, which may be the problem you are having. Some have found stability manually setting timings to 8-8-8-24, 1.4v  Apparently, this is a wide spread thing with AMD boards.

First thing to try is swapping the memory to the two blue slots. Failing that build the whole thing up outside the case. IO know that you have only just rebuilt it but that is the best way to troubleshoot. Lay something like a towel (Anti static)down on a table and put your components together on there.

The only difference in the coolers as oggmonster explained is that the extra wire is to enable control of the fan's speed and measure it. You may need to turn the alarm off in the BIOS if you only use a three wire connection. I take it you do have a buzzer installed? Are you getting any POST beeps to let you know what the problem is?

Just to add to this, I am running the Noctua NH-NH-D14 Air cooler and as DM states you want to turn off the CPU Fan Fail warning and also the CPU Smart Fan Control. I originally had issues getting the cooler fans to spin up but am now powering them directly via the PSU. This is a much safer way to run them and as they are so quiet running at full speed it is not a problem.

What he said, sometimes the fan headers on motherboards have a tendency to blow. Majority of the time they just take out the fan header/fan, but there have been cases of it causing the motherboard to fail.
