FX9590 No POST, no beeps, CHV F-Z

[Beentherize]

Here's the situation. When I hit the start button, no POST, no beeps. Fans do not spin, PSU does not turn on. Only a short crackling sound from the PSU is heard.

Hardware:
ASUS Crosshair V Formula-Z (http://www.asus.com/Motherboards/CROSSHAIR_V_FORMULAZ/)
XFX ATX ProSeries Black Edition 1250 Power Supply (http://www.xfxforce.com/en-us/products/all-previous-psus/pro-series-1250w-psu-black-edition-p1-1250-...)
AMD FX-9590 (http://www.cpu-world.com/CPUs/Bulldozer/AMD-FX-Series%20FX-9590.html)
Corsair H110 Liquid Cooler (http://www.corsair.com/en-us/hydro-series-h110-280mm-extreme-performance-liquid-cpu-cooler)
Internal PC speaker (http://www.baybeamer.com/images/cables/InternalSPK.JPG)

I had the system fully built, but had to tear the whole thing down to just the board, PSU, cooler, and PC speaker sitting on my bench.

I have plugged in the 24 pin ATX power, 8 pin CPU, and the 4 pin CPU. PSU is known good.

The vein on the rear of the board lights up when PSU is plugged in. The START button is also illuminated. Pressing the start button results in a short crackling sound from the PSU, but otherwise no other activity. The vein remains illuminated after pressing start. Nothing appears on the Q CODE LCD.

I suspect that it may be that the processor is not supported by the BIOS that's on the board. I'm unable to confirm this as I don't know how to identify the BIOS version currently on the board, nor do I know if the board should be turning on even with an unsupported processor.

Hi Beentherize and Welcome to ROG

The FX-9590 is definitely supported by your MB and regardless of Bios version should post.
As you have no QCode readout, I suspect a hardware failure.
You should not have any crackling sound from your PSU, so something is amiss.
Check all cable connections and plugs to your MB and PSU, smell and inspect the MB for any burned components.
Have only the PSU, CPU connected, no HDD or peripherals. If no QCode then RMA the MB.
How did you determine the PSU to be good?

Please report back.

Thanks, this is good info. I wasn't sure exactly what to expect.

Upon visual and olfactory inspection I was unable to identify any burned components, neither on the face or the rear of the board.

All cable connections are secure, and have been reseated a several times, with the current PSU, along with another known good PSU.

No peripherals are connected to the motherboard at all. Just the items listed above. All parts are sitting on a non-conductive table.

PSU is known good for two reasons. 1) I tested it prior in a known good system. 2) I tested it with a Thermaltake Dr. Power II (http://www.thermaltake.com/products-model.aspx?id=C_00001777)

ASUS Support seems to have arrived at the same conclusion and would like to begin the RMA process for this board.

On a side note, the crackling noise from the PSU is audible only after having been plugged into the CHV F-Z and attempting to turn on the board. Plugging it into the PSU tester, the noise is heard when powering on only the first time (after having attempted power-on with the CHV F-Z). Subsequent power-ons with the tester, the crackling is not heard. Plugging it back into the CHV F-Z causes the crackling noise to manifest again.

Sorry...jumping in late here.

Seeming you have the system out for bench testing I would pull the H110 cooler and replace with the stock CPU fan/cooler for testing purposes. There has been issues with the H110 being over-tighten which causes some problems...also an issue with metal washers I believe that someone once posted too?

Circumstantially I don't have an AMD stock cooler since I purchased the OEM version of the FX-9590 (FD9590FHW8KHK). I didn't need a cooler I wasn't going to use since I have the H110.

I took extra care not to over-tighten the screws on the motherboard, and the cooler. Manuals for both, explicitly call out not to over-tighten these screws. I tightened them no more than "finger tight." On the motherboard it was as close to "finger tight" as I could get while using a screw driver, by just using two fingers on the screw driver. For the CPU cooler, the screws have a large textured head so finger tightening those by hand is the method I used.

There aren't any metallic washers in the pump assembly. The screws are affixed to the the pump assembly through sandwiched plastic fasteners.

They're visible in this image here (along with the large textured screw heads):

In between the plastic fasteners is a metal plate which allows the pump to be pressed down securely onto the processor. The plate that the pump attatches which goes onto the back of the motherboard is made of plastic.

OK-I have the same setup on my Thermaltake which I think is actually made by Corsair.

Also are you running the motherboard outside the case now as it sound like something is shorted out somewhere...did you remove the speaker as it may be missed pinned too. Did you pull the graphics card too? Take a look at my link on bench testing too as that may help you isolate the problem. Post back what you find out.

So here I am again. The resolution for this issue was to send the board out to Asus and they updated the BIOS. Once I got the board back it worked great.

I used it for a couple of months, and then I had to put it into storage for the last 6 months. I pull it out and hook it up and start with the updates. A couple of reboots later, the system shuts off, and now the system doesn't turn on just like in my first post. Exactly the same as in my first post.

I have no clue. I'm contacting Asus support again. What a headache.

I'm still on the fence about believing the 4 pin AND 8 pin should be connected at the same time. ASUS says to use the 12 pin and the 8 pin OR 4 pin(not counting the molex plug)

[Beentherize]

I heeded your suggestion:

I plugged in only the 8 pin. Same result.
I plugged in only the 4 pin. Same result.

Unfortunately, the only way to know for sure would be on a new board. But I have troubles myself on this board. I think its time to leave this CVFZ board for another type. I hate to give up like that but Id rather have a computer right now than playing with the box
