Crosshair V Formula - Z Q-code d2

[c4maniac]

I'm pretty puzzled as to this error.

The motherboard goes through a series of codes before landing on that d2 one. It sits on d3 for about 5 seconds then 98 for about 5 seconds then sits static on d2 with nothing on screen. The monitor itself doesn't even power up.

First thing I did was swap graphics cards and it still had the same result. Next thing I tried was to clear the cmos with the button on the I/O panel.

I then striped it down to is simplest config: 1 stick of ram in the furthest dimm from the cpu and no drives nor pci devices save a graphics card. I also tried several sticks of ram in the same dimm. I also inspected the cpu for bent pins and found none. I also took the Li backup battery out for 5 minutes with the power plug unplugged.

After all that still the same code d2.

I looked up the code in the user manual and its: PCH initialization error.

I have done nothing recently to the build cept installed a new sound card about a month ago and a corsair h80i around the same time. I hope its something I can solve myself as this will be the second ROG board to be RMA'ed by me in recent times.

specs:
fx-8350
crosshair v formula - z (1403 bios)
evga gtx 650ti
8gb g.skill ddr3-2133 ram
corsair tx750 psu

Please remove the sound card and see if the problem is fixed up.

I got the board on the bench with the stock cooler on it and the only things installed are the 1 stick of ram in the far right DIMM, cpu, and nvidia 650ti. I cross tested the graphics card and ram and PSU all those work fine on other systems. I don't have another board to test the AMD cpu which is too bad but I don't see anything obviously wrong with the cpu. There was about a span of 3 weeks with the corsair h80i and soundcard where the machine did work fine. I only did a light OC with this board at 4.2 for a time after I had the corsair cooler installed. Only used the built in asus software (turbov evo) to do that.

I'm thinking its northbridge controller stuff maybe. But I don't know.

I currently have the psu I was using in the amd rig in my old p8z77-v pro board with i5-3570k. Working fine.

Ah right I did not pick up that the board had/has worked perfectly. Can you roll back with a systems restore to before you installed the sound card please.

Since the error the screen doesn't even turn on. I've tried 2 different graphics cards which both work in other builds. This board only has a option to clear the cmos. There's no usb bios flash back or anything.

I don't know what happened but I was able to boot the board up. So I flashed the bios with the lastest and greatest 1503.cap. Everything seems to be fine so far. Going to add the g.skill ram and see if I can boot into OS. Good thing too I start school next week and kinda need a computer to be working.
