Hi. Thank you for tasking the time to work on this and share your results after working on it for hours until 4 am. I must say that Iāve done all that, even removing the CPU from the LGA 1700 socket and verified that there werenāt damaged pins in it, and visible damages in the CPU. There were none as I watched them closely thru a magnifying glass. I have also dissembled the rest of my PC, checked slots (for damage or dust), device pins and cables (when it applies) taking care of blowing them to remove any dust specks if there were any, and for cables being set in PSU side, Motherboard, PCIe GPU card, SATA, etc. I even checked the connectors from FANs to headers as well as those from Motherboard to front buttons (PW, Reset, USB ports, etc.). Then reassembled it again as it were new: clearing CMOS, Button Flash BIOS with latest version for this MOBO on MSI site, and inserting and testing on POST if each inserted component was detected. In the case of memory sticks (4 x 32GB each) I have done a very long process of testing each DIMM (on slot A2) using MemTest86 running overnight (it takes long), then leaving a good one and testing the other three (one night each) on Slot B2. And so on until I was satisfied that not the DIMS nor the slots had trouble.
Regarding BIOS settings; Iāve have not, aside from: changing POST settings to enable beep on POST, disabling MSI and Windows Fast Boot, and, in the overclock settings, changing the CPU cooler from Water Colling to Air Tower cooler donāt . For the rest, I havenāt made any changes from the āOptimized Defaultsā I do not overclock so, I have not change voltages or anything else related to overclocking. I donāt even use XMP, although I have tried enabling it and disabled it with same results. The only other thing I have changed in BIOS is the source sensors for the PWM Smart Fan function according to the case fan position and function (intake or exhaust).
At one point, since when I power-off the PC I also switched off the PSU plus the UPS to which it is connected to the AC. I thought it might be a CMOS battery problem; so first I bought to new ones and tested. Same result, then I stopped switching off PSU and CPU, but same results. PC starting directly to BIOS, where I corroborated that my settings were still as I left them.
There is a weird thing, though, when my PC starts directly to BIOS the WD Black SN850 as boot drive is not detected, but if I run secure erase from BIOS, it restarts, and surprise! th WD Black SN850 is detected. When that happens I dont erase, let it reboot and the drive is āStillā there, so I have run NVMe SSD test from BIOS and no errors were detected. Same when I finally manage (after many shutdowns and cold boots) to boot to Windows (SN850 detected) Iāve run WD Dashboard Extended SMART test, as well as Windows Disk Management test and both came out trouble free. Also from Dashboard my WD Black SN850 was updated to Firmware Version: 614900WD.
This is my build:
- MB: MSI PRO Z690-A (DDR5 version, no WiFi)
- CPU: Intel Core i7-12700K
- RAM: 128GB Kingston Fury Beast (4x32GB)
- Storage:
- 1TB SN850X (OS Boot Drive) on Slot M2_1 Between CPU and PCIE_1
- 4TB WD Blue SATA III SSD on SATA Port 1 (dunny fact, not on MSI QVL list, but itās always
detected by BIOS)
- GPU: MSI GeForce-RTX-3060-VENTUS-2X-12G-OC
- OS: Windows 11 HOME (64 BITS) release 22H2
All drivers are updated using:
- MSI Center Live update feature
- Microsoft update from Device Manager
- NVidia latest WHQL update for my GPU
Final note (knock on wood): today my PC booted to Windows right away on power on. Some times this happens for 2 to 3 days and the the problem starts again.
