PC failure occurred following a system crash.
My new PC started up properly after assembly, let me install Windows 10 Pro. It handled several CPU and RAM stress tests until it crashed with a BSOD, displaying a KMODE_EXCEPTION_NOT_HANDLED error. Shortly after logging in, it bluescreened again within seconds, showing another error code. This sequence repeated multiple times, each time presenting a different issue. Eventually, the system stopped showing any video output at boot. The fans still turned on, the GPU lights stayed lit, and my motherboard’s debug LEDs flashed briefly—red for CPU, yellow for DRAM—for a short duration before shutting down completely. No VGA or green Boot lights appeared. Despite these signs, no video reached the monitors, and the USB keyboard lights never activated. I experimented with using only one DIMM, swapping DDR5 modules for DDR4 ones, removing the GPU, connecting directly to the motherboard’s video output, replacing my PSU with another identical model, and even sending a new motherboard. All attempts failed to resolve the problem. My monitors remain functional when connected to an older machine. I returned the board for replacement, but it didn’t fix the issue. I’m running out of options and would appreciate any guidance or support.
Connect the storage to another machine and retrieve the dump files. Navigate to X:\Windows\Minidump (using the driver name from the other machine) and verify the presence of any dumps. If available, return to the Windows directory and move the Minidump folder to the Downloads folder—use your desktop if needed for file syncing. Compress the copied folder and send it via a post. Please adhere strictly to the steps since Windows doesn’t allow changes in that area. Did you try using a different motherboard as well?
Confirm the details: did you attempt to install DDR4 DIMMs in the MSI PRO Z790-A WIFI ATX?
I confirmed the DIMMs used in the MSI PRO Z790-A WIFI ATX are DDR5, not DDR4.
The system only has one M.2 slot. You can attempt a recovery by connecting it to that slot and booting from an Ubuntu Live USB, or you could try booting the SSD directly.
How do you install the CPU cooler? Do you equally tighten the two main screws while the device is laying down, or do you mostly full tighten them each at a time while the device is stood up? I ask because there's always the possibility that an uneven torque applied to the CPU while tightening down the cooler cause a slight tolerance gap in the CPU socket to shift the positioning enough to cause contact issues with the socket. It's a slim possibility, but still exists. So, the goal would be to mitigate the potential for you to twist the CPU in its socket or shift it laterally by eliminating/reducing asymmetrical force vectors while installing the cooler.
I gathered the Minidumps files from an Ubuntu live USB on my machine and included them here. Let me know if you can view them or require more details. Thanks for your support! minidumps.7z
Do you have any USB connection from Microdia? I’m having trouble finding the device ID and haven’t come across Microdia before. A quick search reveals several companies using that name, so I wasn’t sure which one. If you remove it and check again, will the issue persist?
