Solid Red CPU Q LED - ASUS Crosshair V Formula (Fails to post)

post #1 of 4
Thread Starter 
SPECS IN QUESTION:
ASUS Crosshair V Formula Motherboard
CoolerMaster Silent Pro 1,000W PSU (Gold)
AMD FX 8350 Vishera
G.Skill Ripjaw X RAM (8GB Sticks, 1866MHz)


Hi all.

I finally got the last of my parts for a build i've been assembling over the course of a few months.
Spent all last night and this morning assembling it (this is my third full custom build), take it upstairs, weary and tired, and press the power button.

LEDs flash up, fans turn on, and... nothing. No loading screen, no BIOs messages or anything. Just a bunch of nothing.
Looking inside I notice that among all of the green LED status indicators, there is a single solid red one. "CPU Q LED" which apparently represents an unknown CPU related problem according to the motherboard's manual.

Everything in this rig is brand new, out of the box, so I assume off the bat that maybe I messed up my wiring. I do a quick overlook, re-tighten my cables, etc... and still no joy. (I have also tried switching my 8-pin ATX to be 4-pin.)

I removed my RAM and re-seated, to no avail. Removed the CMOS battery for a bit and set the jumpers to clear CMOS as well, which had no effect. Reseated the CPU as well, with no luck.

I just brought it back down, undid all of the work of last night and removed everything but the motherboard, CPU, PSU, and 1 stick of RAM. Powered it up, and of course, all green lights with the single solid red CPU Q LED shining in my face.

So, maybe my CPU was DOA... I went and retrieved my old build from the floor in my room, gutted the case, and retrieved my newly-to-be-replaced CPU, which is an AMD Phenom II x4 955 BE. I install it in the new motherboard, and... you probably saw this coming, but yeah, the LED is still illuminated.

Lastly, I figured, maybe it's the motherboard itself. Maybe it's not even powering up the CPU. So I (stupidly) touched my finger to the Phenom, and promptly scorched my finger. So it's definitely delivering power...

After cursing loudly a few times and dousing my fingers in cold water, I came here, hoping maybe someone could give me some sort of idea of what may be the issue.


Thanks again.

it could be your mother board.

Try this
unplug pc
take out the cpu and bios battery.
Press and hold power button for 10 seconds.
put bios battery and the 955 back in the mother board.
Plug in and boot.

See if it boots.

Thanks for the reply.

I did as requested, but still no luck. I also tried again with a VGA installed to see if I am getting any sort of response back, but all I got was a blank screen. It didn't even attempt to boot up (the VGA powers up fine, though. As does a CPU fan and whatever else I plug into the board pins, or directly to the PSU.)

qwell if it doesnt boot with the 955,,,i would say you got a bad board,,,keep that 955,,the replacement board will probably need a bios update for BD or Vishera,,,if you can try to get the secound version of the crosshair v,,,the first version had grief
