" rel="nofollow - Hello. I'm assembling a computer on a ASRock X399 Taichi. The other installed components are: TR 1950x cooled by a Noctua cooling tower with 140mm fan, 2x 16 GB Ripjaws 3200, EVGA Supernova 750 G2, Asus GeForce GT 1030 fanless, and a WD 2TB Black HDD. When I turn the power supply unit on, the LEDs above the gear-shaped decoration on the X399 Taichi motherboard light up and begin to change color every second or two. When I turn the system on (using either the front panel button or the motherboard button), the CPU fan briefly spins, then stops, and the hard disk starts up. The decorative LEDs keep changing colors, but the two-digit error display (Dr. Debug) shows no error code. The video card doesn't send any signal to the monitor. I can't turn off the computer using the power buttons on the front panel or on the motherboard. I have to turn the PSU off to turn the system off. The CPU is currently powered through both the 8 pin and the 4 pin connectors, but the same happens if I power it only through the 8 pin connector. The only video card installed at the moment needs no power cable. The RAM modules are installed in the B2 and A2 slots. I attempted using only one RAM module. I checked that there are no standoff screws out of place. I re-seated the CPU and re-insert everything from scratch. I cleared the CMOS. I currently detached the front panel connections. Nothing changed. I exhausted my resources. This is my first computer build. What can I try? Thanks! |

| I just powered the computer after removing the video card: same result. |

" rel="nofollow - Now I disconnected the power supply for the CPU and the result is the same. So I assume that, for some reason, the CPU is not being powered even if (apparently) it's physically connected to the power supply unit. Or the CPU is broken. Or, despite I already re-seated it as per instructions from the AMD video, it's still not installed correctly. I don't know how to check this and how to fix the problem. Does anybody have a suggestion? |

" rel="nofollow - Is there power getting to the board at all? If you plug in a LAN cable to the board do you get any LEDs on the port? If you have not tried already, remove the board and try running it outside of the case, you can rest it on top of your motherboard packaging box. If it powers up in this way then you have a short somewhere, most likely a misplaced standoff. Double check everything before putting it back together.

In my first message, I wrote: "When I turn the power supply unit on, the LEDs above the gear-shaped decoration on the X399 Taichi motherboard light up and begin to change color every second or two." So the motherboard is obviously being powered. I also explicitly mentioned that I checked the standoff screws: "I attempted using only one RAM module. I checked that there are no standoff screws out of place. I re-seated the CPU and re-insert everything from scratch. I cleared the CMOS. I currently detached the front panel connections." |

Could you list your full system specs for us so we know the following: PSU brand and model RAM brand, capacity and model number GPU brand and model I get that you are stressed out trying to get your new build working, it happens to us all. It is especially stressful when dealing with expensive new hardware. That said, bare in mind you are here seeking assistance so try to keep your posts friendly. I get it, I missed some of your post. A Threadripper system was a very ambitious first build, even pros have trouble with their first threadripper build. Mounting the CPU alone can take 4 - 5 tries to get right. Patience is crucial, especially with such a challenging build. Take your time and make sure to walk away from the build every now and then to clear your head and cool off. When you are angry you are not thinking clearly and risk damaging things. My advice: 1. Pull the board out of the case and remove the CPU (yes, again) 2. Connect only the power to the board (CPU and 24 pin), install one stick of RAM, GPU and CPU 3. Clear CMOS 4. Power the board outside the case resting on the motherboard box When you reinstall the CPU outside the case it will be much easier to see if the retaining brackets are seating properly. Double and triple check everything and really take your time. Calm, steady and cautious. Post back with your specs and any changes, good luck. -------------

he should be getting post codes even without any cpu/ram/gpu inserted ------------- http://valid.x86.fr/diq4l4" rel="nofollow">  http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |

Hi, Xaltar. Yes, you missed important parts of my message, and yes, I've been inappropriately harsh in my reply. I appreciated very much your calm and kindness that you showed. After that message, I took the computer to a shop. The technician actually didn't do anything more than what I did (he did less, actually), and confirmed that the motherboard didn't work properly. Subsequently, I asked for a Return Merchandise Authorization. That was granted, and I was refunded today. I ordered the same motheboard from another supplier, and I will let a technician finish this part of the assembly. Thanks again for the support. |
