HELP ! - Urgent - ASRock Z68 Extreme4 Wont power up

Shaddow · 24 May 2011 at 21:05

Help!!!!!

Hey guys hope you can help; I'm really pulling my hair out on this one.

I'm now on my second Extreme4 board (1st one RMA'd) and I have exactly the same problem with the second one!

Basicly; I cannot get any sign of life out of it at all.

I plug it in, have CPU, RAM installed and hit the onboard power button and nothing.

(CPU 2600k, Ram 8gb Vengenance)

There does not seem to be any on-board Led to indicate power (unlike my other board the Asus P67 Deluxe - it had a small blue led)

Could there be anything that is causing this not to boot up?

My Asus board would show signs of life even with no Ram and no CPU installed!...

So much for onboard ASRock Dr Diagnositic !!

I've tried another PSU (and my existing PSU works fine with the Asus board)

Any suggestions welcome...

Thanks

Are you sure you have all the power cables plugged in?

24 pin and 8 pin on the motherboard.

Any 6/8 pin connectors for graphics cards.

Motherboard standoffs installed?

Do you know the CPU and RAM work?

Hi.

Ok so the Extreme4 has 20pin with optional extra 4, and 4pin with optional extra 4.

I have tried both combos.

I've not plugged in a graphics card (it has built in graphics)

I currently have the board 'out of case' for testing but when it was in the cae all the standoffs were installed and none in the wrong place.

The CPU and RAM were working fine. (I'm awaiting my B3 replacement Asus board now)

Thanks for quick response!

What do you mean by you've tried both combos?

You need to plug all the 24 pins in and all the 8 pins in at the same time.

Shaddow · 24 May 2011 at 21:27

I've tried with 24 & 8 Pins and 20 & 4 pins (Both combos)

There are 2 stickers over the spare 4 pins and the manual says they are optional; but just to confirm I've tried with and without the extra 2x 4 pin connectors.

What are you sitting the motherboard on while it's out of the case for testing?

Are you sure you've turned the PSU on?

Have you checked the fuse in the plug?

Surveyor · 24 May 2011 at 21:39

Check the clr CMOS button is not pressed in on the back panel.

Shaddow · 24 May 2011 at 21:42

Ok mother board is in the case laying flat on floor, inside the insulated foam casing it came in. (no metalic contact with anything else)

The PSU is ON; the Fuse works as when I plug in my Asus board it all fires up fine. (I've also tried a different PSU)

I'm wondering if this board has some special monitoring that checks if keyboard is plugged in or something stupid (power saving related)?

I can believe one DOA board; but 2 from different sellers?

Shaddow · 24 May 2011 at 21:44

I've checked the CMOS button is not pressed; I've tried pressing the CMOS button and also tried removing the battery for 20mins.

As you have it in the case try connecting the power switch from the case and starting with that.

Would rule out a fault with the switch on the motherboard.

Try with just one stick of RAM or some different RAM if you have it.

Shaddow · 24 May 2011 at 21:59

I've have tried the Case switch.

I have just had some new G.Skill Ripjaws 17000CL9D mem arrive today from OC so I will try that..

But I'm pretty sure I should at least see the onboard numeric diagnosic led light up?

Should it not indicate simple things like 'no ram' , 'no cpu' ?

You'd have thought so.

They normally start at 00 when you switch on and them work through a series of codes as checks are carried out.

Shaddow · 24 May 2011 at 22:22

Ok tried with new ram; still no joy.

It's Dead Jim.

Surveyor · 24 May 2011 at 22:32

Not looking good.

This is a long shot and based on very old tech. Quite a few years ago I remember spending a whole day trying to get a new mobo to boot. I tried every combination of everything and then I noticed a little bit of plastic under the cmos battery (do mobos still have cmos batteries???), pulled that out and it booted.

Is it worth plugging a GFX card in ? I have just rebuilt my PC around the same board, and figured I would start off with the integrated gfx.....but got no output to monitor > plugged in my trusty GTS250 gfx card and bingo !
That said, though, don't recall if the board failed to power or not without the discrete gfx.....but worth a shot ?

Shaddow · 26 May 2011 at 19:27

Thanks all, I've tried with 1 and 2 580's. I've also tried removing the battery for 20mis. Still no joy!

Just had the same issue, look at your Dr Debug on the mobo see what code it says.
If its the same as mine it will say 45. If it does, try using one single stick of ram and work your way down the slots.
Just had to RMA mine as it showed first 2 slots dead

Also try booting with no RAM at all.
Seems to be some issues with RAM slots on these.

I was going to order the ASRock Z68 Extreme4 board tomorrow but the problems with faulty boards are putting me off now.

If you read the thread you'll see the OP is getting nothing at all from the motherboard. No signs of life and nothing on the Dr Debug display.
