Hello, I am in the process of building a new PC. Components are as follows:
After connecting every component to the motherboard I booted up the PC loaded a Manjaro live CD and started a new installation to a SATA HDD. During the installation the monitor turned off and nothing happened anymore. LEDs still pulsing, fans still running. Restarting the PC gave the same (non-)picture. I am getting no boot screen, no BIOS logo, nothing. The monitor stays off. There is no signal. The computer is "on" (LEDs pulsing, all fans spinning) and I get POST codes from the Taichi. But nothing else happens. The POST codes I see (not in that order and I'm sure I've missed a few) 07, 14, 15, 3B, 3E, 54, 60, 63, 7A, 90, C0 The codes are always looping. Can someone deduce what is wrong? Here is a list of what I've already tried. Everything without a change:
The motherboard case says that the board is ready for the Ryzen 3000 series. So it should be ok for a 2700x, right? I don't know what to do anymore. The only thing left it could be (in my mind) is a broken CPU or a BIOS not suitable for my system. What can I try? What could it be? |

hello @sanklamm Set ram speed 2133mhz to install windows, if all OK, means ram parameters need manual adjustment, may be cannot use XMP. May be!!! ------------- x370taichi@3.50gen4 AX750 Optane900P SN770 3800x PosdonZro4 BarrowPWM-17w>420x140x28 XFX SWFT319 6900XT MSI RX560 LP to get Fluid Motion BlueskyFRC 75hz |

hello, the problem is, how can I set the RAM speed if I'm not even able to get into the BIOS? As I said, the monitor doesn't get a signal. |

| then you'll have to reset cmos i'm afraid. |

Is there a special way to reset CMOS apart from disconnecting PSU, removing battery, draining system of left over current by holding the power button for 20 seconds and setting the CMOS reset jumper for half an hour? I did that a couple of times. |

| on the x470 taichi, there is a clear cmos button in the I/O-Block. Disconnect PSU, press the button for >5s and you are set. |

yeah. that too. Did this the first 20 times. Then resorted to the aforementioned measure. I have a feeling that I have a bad CPU. But how can I test for that? |

| Did you by any chance forget to connect the ATX12V power supply? |

I plugged in the big 24? pin connector, the 8 pin and 4 pin connector by the CPU. Also the graphics card has its cable plugged. The PSU is a Corsair 750W. |

Make sure the RAM is properly seated, sometimes the slots can be very tight on a new board. Use a single module of RAM in slot A2. Check the sticker on the BIOS chip to see what BIOS version is installed Try turning on the PC and just leaving it for an hour. If all else fails, return the CPU for replacement. With Post codes the only one that matters is the last one on the display before it boot loops. In this case I am guessing C0 which is AGESA Boot Load initialization. -------------

| I also used this PSU to power the old Intel mobo on which I've tested the graphics card. Only the 8 pin connector had no place to put it in. So that cable is not tested. But the PSU is brand new. |

Thanks for the suggestions. I am pretty sure the RAM was properly seated. It gave clicks on both sides of the slot. I've tried about every permutation of RAM in those slots. The sticker says 1.30 but is striked through by a black marker. Maybe because it was upgraded to support Ryzen 3000 series. There was an additional sticker on the mobo box saying "Ryzen 3000 ready". I guess for that a flashed BIOS was necessary. So I'm not sure which BIOS is installed. Yesterday I've tried leaving it running with the new 4GB Ram module (I've bought for troubleshooting) for about 30-45 minutes. A couple of hours ago I've brought mobo, CPU, graphics card and RAM to a shop nearby to check for damaged parts because I didn't know what to do anymore. And since I've already RMAed the mobo - which seems to not have been the problem - I would like to know what is actually broken before RMAing anything else. We'll see what they find. This PC building project turned out to be a terrible experience. |

Good call taking it in to be checked out for you. Let us know what they find  -------------

I just got the call. The CPU is fried. With another 2700x the system boots right up. The technician also told me that the POST code cycling is due to not finding a (for the boot process) vital component. So the board looks for that device, does not find it and starts all over. Now I hope that I get the CPU RMAed. Whish me luck :) And thanks for all the tips. |

I suspected as much, good luck with the RMA  -------------
