So I went out of town for 2 weeks and came back and when I tried to turn the PC on, the power supply fan turned on, case fan spun, red light on front of case came on, but display showed "no connection." Took the bios battery out and tested it with multi-meter and it was fine. Put it back in, and same thing. After the 4th or 5th try, it finally booted but came up with a black screen that said: "We detected a new processer, which will change the data/structure of the storage for firmware TPM. If you did not apply TPM function, please press Y to continue, otherwise please follow instructions below... etc" I pressed N to keep precious fTPM and it then booted up normally. Today, I turned on the PC and had the same problem. But I tried a bunch and still couldn't get it to work. So I took the Power supply out (Corsair rm1000x) and did the paperclip test, and tested voltage on all pins. Tested out ok. So I plugged it back in and fired it up... and got that same "new processor" message. Only thing I can think of is there's a weak cap on either the power supply or motherboard somewhere that will eventually completely fail. System isn't that old. Built in Feb 2024. Mobo is a Asus prime B550 plus. CPU is Ryzen 7 5800X3D. Memory is 64 gigs of corsair (I forget the exact model) Any thoughts? |

this is odd - only thing that comes to mind is that you took a bios or firmware update. Verify that CPU-Z still shows the right motherboard / bios version. I have similar but lower end version of that hardware and just wondering what happen. My part is not the 3d thing. Oh; BIOS updates can and will require that the TPM might/will be cleared. |
The last thing a tyrant wants is their ideas to be judged on the battle field of truth and justice.

Thanks, I will look into that. Maybe. I'm afraid to turn it off now.

You've got a point, but that's weird. You usually have to go out of your way to update a BIOS. That's not a typical "windows" or automatic update thing and you usually have to download the new BIOS from the manufacturer onto a flash drive and do the install outside of windows on startup. |

I just installed the latest stable bios (still about a year old, but better than the previous one from 23). Finished that and it went to that same tpm screen when it went to reboot. But this time, some of the text was in red (oooh). This time I selected Y to reset fTPM. Booted up. Then I shut it down and gave it a 10 second count after I heard the power supply click off. Started it up again and it booted right up. Fingers crossed... maybe that fixed it? I'll turn it off tonight when I go to bed and see if it boots up in the morning after its sat overnight without power. Assuming we have power tomorrow morning... (yay, ERCOT). If it boots right up, I'm going to hazard a guess that something that automatic windows update did fucked with or does not play well with that TPM thing and updating the bios and resetting TPM fixed it. If not, I'll lean towards it being an actual mechanical issue. |

Which still seems weird. Maybe some obscure thing in there that didn't play well with the AMD software? I dunno. |

Fan comes on for a few seconds, then shuts off. Which is normal. But then if I turn the switch off, it won't come on until I unplug it and replug it. I filed a warranty claim. Either it's failing under load and corsair will discover that or they'll tell me it's fine and that will narrow it down to the mobo. If it's the motherboard, I won't be terribly surprised. Asus has become kind of a disappointment in recent years. |

Replacement power supply came in. Did not fix the issue. 99.9% sure its the mobo. Its still under warranty but Asus' rma system is giving me a headache. And my crystal ball tells me that's by design. I'm done with asus. This mobo was kind of a turd out of the box anyways. Bluetooth and wifi never worked. BT device would only connect if held inches from the pc, lol. For 100 bucks I can have Amazon send me a basic gigabyte b550 and have it in my hands in less than 24 hours. I've been using asus boards since the k6-2 days. Not sure what happened but they are not what I remember |

Didn't realize I needed to screw in the WiFi rabbit ears because they put the BT in there too. And I also feel Asus has been on a decline. Their pricing is nuts on certain product lines. |
The plane flew, admit you're wrong and get over it.

I've been using asus boards since the k6-2 days. Not sure what happened but they are not what I remember IMHO, I wouldn't go gigabyte. My wife's computer has a gigabyte mobo with an i5 and DDR4. I hate that thing. Bios sucks where basic things like M.2 settings are poorly labeled or hidden and required if I want to run NVME vs SATA M.2 drives. It also takes 1-5 minutes to post EVERY time it boots. It's done that since day 1. I run a ASRock B650. It's been a great board with my Ryzen 7 and DDR5. |
