Question How do I fix Stopcode: "Machine Check Exception" ?

Jul 25, 2021
Recently I built my first pc, I installed the windows 10 OS via USB, set up goes smoothly.
I install a driver for my WiFi card via a different USB stick to get it to work, and once I have a Internet connection asus Q-Installer says it will automatically find and install new drivers for all my components.
However after leaving the room to get a drink I return to find the computer has restarted and has frozen on the boot screen where it shows the ASUS logo, as in the picture attached. I wait 30 or more minutes before turning the pc off and on again, and am meet with a blue screen showing with the stopcode: Machine Check Exception.

Now everytime I turn on the pc it either loads a screen saying "preparing automatic repair" and freezes or a screen with an ASUS logo and a loading wheel and freezes.

I can still access the bios.

How can I fix this? Any help would be so greatly appreciated and is needed.

Heres a list of my parts:
CPU: intel i7 9700k
CPU Cooler: Gamemax iceberg 240mm aio
Motherboard: ASUS PRIME Z390-P
RAM: Corsair Vengeance RGB pro 16gb 3200mhz
SSD: Adata xpg s40g 512gb rgb m.2
PSU: Be quiet! System power 9 700w cm
PCIE WiFi adapter: TP-Link T6E AC1300 Archer Dual Band Wireless PCI Express adapter.


Win 10 Master
asus Q-Installer
first I heard of this application before - https://www.techpowerup.com/248827/asus-z390-motherboards-automatically-push-software-into-your-windows-installation?cp=3

It seems Q Installer is from the bios. I don't know good it is at its job. I would honestly go to Asus website and grab latest drivers and make sure you are up to date.

Machine Check exceptions are errors called by CPU but not necessarily caused by them. I think it can be a driver problem.

you might find its best to turn off the feature that pushes Q Installer onto windows and see if reinstalling windows without it fixes errors or not.
