Hanging and rebooting 2 laptops when idle. Why?

Question

Windows

So, there are 2 ASUS X751N laptops, bought more than a year ago with an interval of 1 month, used in accounting. Around October 15, the following problem began on them: if you do nothing and leave the laptops alone, after a while the 1st reboots, the 2nd freezes tightly. Both had a Win10 Home Single Language license, on the first version 1803, on the second 1804. At 1m there was a dead battery (from about May). Analyzing the event log and minidumps, errors No. 124 (WHEA_UNCORRECTABLE_ERROR) were found and periodically cursed at WDNISDRV.sys (Windows Defender).
What I did: -
ran antiviruses and antimalware - everything was clean
- removed McAfee antivirus, turned off the defender, updates, sleep modes, all energy savings - did not help - stable after 9-11 minutes of inactivity reboot.
-checked the smart disk, ran the checkdisk, victoria, RAM check - everything is fine
-made an installation USB flash drive with the Win10 utility from the microsoft website - installed the system without formatting with saving files - after loading the story repeated: 9-11 minutes and reboot (WHEA_UNCORRECTABLE_ERROR)
-booted in safe mode - everything works and in idle mode it does not turn off.
-looked at what devices are disabled in the manager in safe mode (some kind of synthesizer and hyper-v driver), booted up in normal mode, disabled (did not delete) them, plus disabled the battery in the manager), rebooted - everything works
-began to turn these on one by one devices and check, then reboot - eventually turned everything on and the system works fine.
On the second laptop, I didn’t reinstall Windows, but only rolled up update 1809 and did the same operations with devices as on the first one (on the second laptop, the battery was alive, but turned it off anyway) - in the end everything works.
The fact that both laptops work is great, but still the question haunts me: what kind of trick was this? What is the problem with firewood or updates on intel or exactly Asus's? Has anyone experienced something similar?

Answer 1

disabled defender, updates

Turn on updates and update.

Answer 2

With Asus, it happens such crap that for the sake of stability it’s better to install native driverpacks, and then Windows updates come and the circus with horses begins ...
