Crosshair V Formula No Boot

I recently purchased computer parts to build a new PC for my Birthday which was on July 5th. It came in yesterday and I'm having really bad issue's with this motherboard. After countless hours of trying to troubleshoot this I could not find the final verdict but only the supporting factors of it.

First off, when I assembled the PC and turned it on for the first time, it ran for a fraction of a second and shut right back off. I was like WTF? So I realized something was going wrong. I ended up taking the PC out of the case and putting it a-top the original motherboard box and assembled it on there with the bare essentials need to run it. PSU, RAM, CPU, GPU just what is needed to get it to show the BIOS at least.

So here's what I came up with, when I have the 8 PIN or 4 PIN or both connected along with the ATX Power Connector, the PC will run for that fraction of a second all lights and fans turn on as well and shuts back off right after that. Keep in mind the Power On, OC & RESET buttons on the Motherboard are Lighten up regardless if the system shut down along with all the fans and other lights. So the PSU shouldn't be a problem since it's drawing power still. It also does not ever reach BIOS, the monitor still shows no signal. I tried two monitors to debunk them, a CRT via VGA/DVI & LED Monitor via HDMI.

Now when I remove the 4 PIN or 8 PIN or Both and keep the ATX Power Connector in, the system Fans & Lights will run continuously without stopping until I manually turn off the PSU while still no sign of a boot to BIOS. And reading the manual says that you need 4 or 8 PIN to be connected in order to boot. This debunks that no matter what power configuration to the board, it will not boot regardless.

I furtherr stripped the board down to No GPU or RAM. My case speaker will not even get to the point of beeping with these uninstalled. I tried 1 RAM Stick, Removing CMOS Battery.
Still same problem with either shutting off almost instantaneously or fans and lights continuously going with both no sign of a boot / bios. So there is something seriously going wrong with when I plug in those 4 & 8 Pin and possibly the whole motherboard in general.

Very dumbfounded by this please help me.

  1. I'm having a similar problem as above, with a very similar build. Curious if you've found a solution?

    The hardware in common is:

    Processor
    Motherboard
    Memory

    I've completed all the troubleshooting steps you've mentioned, but I'm curious if you've tried the RC Poster utility while attempting to boot?

    Upon assembly I plugged my laptop into the ROG Connect port on the board (to avoid having to set up a monitor/find a keyboard etc.).

    I tried several times to boot, and the RC Poster utility kept stopping at "Check CPU" (String) 0005 (Code).

    Assuming this was a BIOS update issue, I hooked up a keyboard and monitor, only to discover that I have no display regardless of which PCIe slot I use or which of the 2 GPU's I install (this is an SLI build).

    At this point there's not a whole lot more troubleshooting I can do, but I intend to test a different CPU, Graphics Card, and Memory before requesting RMA on the board.

    I would be interested to see the results if you have the equipment available to check your POST messages using another computer and the ROG Connect utility.
  2. Read some reviews on my PSU and someone stated it had not enough juice to even power up his motherboard. To rule out the PSU I returned it today and will get a Gold Certified PSU to see if it will hold up. The system truely is powerful to begin with so maybe the PSU could be a suspect. Or maybe Thermaltake just wont cut it. Will try with an Enermax instead. On a side note i've already had it RMA'd so we will see if I can rule out the motherboard too. Ill keep you posted, you the same. Thanks
  3. After speaking with Asus Tech Support, I decided against disassembling my only other desktop for parts to continue troubleshooting and started the RMA process on the board.

    I suppose the Power Supply could be an issue, but considering the board still wouldn't boot in an absolute minimum power configuration on the bench, and it's well over 200W more than the manual states as required, I find it unlikely.

    As far as I can tell at this point, it's either the board or the processor, and based on my limited experience with both and the reading I've done online I'm leaning towards the board.

    Let me know if you get your new one up and running, I'm looking at 2-3 weeks before I get a replacement board back.
  4. Will do. I got me a Corsair AX1200 PSU off NewEgg so Im looking at having that in by Wednesday and the Motherboard on Tuesday. Keepin you updated.
  5. I have the same problem except with the ram and the motherboard.
  6. Krytical go here http://www.asus.com/Motherboards/AMD_AM3Plus/Crosshair_V_Formula/#CPUS

    If your cpu is not the EXACT model your pc won't run, you may need a new processor. Read my post "crosshair formula v compatibility"
  7. My CPU is listed there.
  8. Fixed my issue, My cpu fan/pump was not plugged into the "cpu fan" power socket. therefore the board did not recognize a heatsink as a precaution it immediately powered off to make sure the CPU would not over heat. All is well and working now, it boots.
  9. I'm currently typing this reply out on the newly built PC.
  10. Congratulations, any changes other than replacement mobo and power supply?
  11. That was it :D

    i also have same issue,with a 990fx asus board..the sabertooth,same ram,and a verified from processor list.

    wasnt the cpufan powerconnector glitch,memory is fine,its either cpu or board.its not the 8pin power connector tested that.

    it does seem like a very short time into post then shutdown...im leaning toward safety feature gone wrong/diisfunctional on board
  13. I have had the same issues, But what it came down to is following the QVL for the board, you can download this info from asus,
    Also , i did manage to get the triple channel ram stable as well, but with a serious down clock ( 10 10 10 27 )

    Being this is such a new board Just do what you can for now and im sure there will be bios updates, Asus tried to RMA my board but I managed to make it work correctly after about a week of trouble shooting.

    Sadly, Asus wouldn't give me much support on this, but because i was using EVGA GPU's their support help me out a ton, Microsoft did this as well .

    This is not a board for someone just wanting a plug and play. But it is well worth the effort once you get it working
    Specs :

    Asus Crosshair V Formula 990fx
    AMD 1100T @ 3.8 ( I haven't OC past this mark yet )
    EVGA 590 x 2 SLI
    16g Crucial "DUEL CHANNEL DDR3 @ 1600 Mhz - 7 7 7 21 " NOT TRIPLE CHANNEL DDR3 " ( triple channel will run @ 800mhz 10 10 10 27 )
    Corsair H70 Liquid cooling
    OCZ 240g SSD x 4
    Windows 7 Ultimate 64
  14. mine was a bit simpler than most...motherboard screws too tight....shoulda checked that first
  15. im writinf from my rig btw...im lovin amd atm...its my first build and my first amd
  16. >.< you guys are making me mad by coming up with the results for yours. mine is doing the same thing as the main topic....i havent gotten the fan yet,so mabye thats it. i already had a fan but it had a 3 pin connector, and the input for the cpu_fan has four so i bought a 4 pin and it should come today.

    rig:
    crosshair v formula
    amd phenom iiX4 3.6ghz
    western digital caviar green 2tb bare drive
    radeon 6850 xfx
    1000w psu by xion
    crusial ballistix 2x4 ddr3 pc3 ram
    rosewill challenger case

    anyone know why it would not work, other than the fan??

    Hey, glad you got the issue sorted, well done for that.
    I just wanted to tell you what an 80+bronze/gold/silver/platinum/titanium power supply was as i think you have it slightly muddled :P

    The W of a power supply is the maximun amount of W that your power supply can let forward from the mains.
    The certificate (80+) is how efficiently the power supply uses the power. (How much W is lost through heat rather than being sent to components.)

    Hope you enjoy the motherboard, it's a great board as i have one too :D
    Run the overclocking program though for your CPU.
    Its safe and well worth it :D
