Windows 10: Random power down or auto wake-up and start restart loop issue after window update

Hi,


After I updated widows 10 using windows update function, my system because very unstable -

restart loop a few times and no post after that. The pc power button is no longer working until I cut the power and drain the power completely.


The symptom starts with random power up automatically, then it shut down by it self a few minute later.

Then, it starts restart loop ending power cut by motherboard circuit break.


Tried troubleshooting for last four months

1 I replaced the PSU, CPU, motherboard, SSD, and ram. Still the same problem occurs.


2 Updated windows 10 build 1909 to 20H2, but has the same issue.


3 Fresh install the build 1909, as soon as I run and install the windows update, the reboot loop starts and it kills the motherboard power circuit.


4 Finally I tried three different PCs: two are using MSI motherboards, and one is using old Dell PC.

I have no issue with Dell PC, but MSI board PCs have the same issue.


Here are three PC specs.


PC 1: Reboot loop issue since update on July 2020

Motherboard: MSI Z97M

CPU: i5-4690

Ram: Corsair DDR3 16gb



PC2: Reboot loop issue since update on July 2020

Motherboard: MSI Z390M

CPU: i5-9600

Ram: G.Skill DDR 4 16gb


PC3: No Reboot issue

Dell Optiplex 9020

CPU: i7-4790

Ram: DDR 3 16 gb


I follow every step what below site suggested without any luck.

Note that fresh installation of build 1909 without windows update does not have this issue I am observing last two days and do not having any random power down issue yet


Please advise.

Best,
