Why does Windows freeze periodically for no apparent reason?

Question

Windows

Good evening.
From time to time I encounter a problem - Windows 8.1 on a laptop occasionally freezes tightly. The screen is on, no artifacts, the picture is clear, but nothing moves, including the cursor. The hard disk does not rotate in such situations, and therefore I simply turn off the laptop with the button (closing the lid so that it turns itself off does not help - the system does not respond to any external commands). This can happen when the system is at rest for a long time - for example, all night. When actively working on a PC, it never happened.
There is only one entry in the logs - "the system was shut down with an error", but this type of error always occurs when the OS shuts down abnormally.
Overheating is excluded, from constantly running processes - only browsers, a firewall and several working softins in the background like nginx or mysqld. In principle, it does not interfere with life, because. occurs randomly and very rarely , but I would like to try to figure it out.
Have you met with this, perhaps a hardware error? Lenovo laptop, used to be Samsung with Windows 7, did not notice this.
Technical details: SMART is normal (there is not the slightest deviation), because. the disc is practically new; memtest found no memory corruption.
Thanks in advance.

Answer 1

Lenovo laptop, too, while it was on Win8.1 (now on 10), there was nothing like that.
This may be due to a power outage on the hard drive. Viruses. Some software.
If you are already so interested, put software for full monitoring.

Answer 2

Look at the power settings - change them.
It looks like an incorrect exit from sleep mode.

Answer 3

Overheat. Keep track of temperatures. In general, computers have this when overclocking is observed. The laptop has problems with iron guts.

Answer 4

Usually the causes of friezes are: A
problematic hard drive - scan, check for bad sectors
Lack of RAM, the system accesses the paging file, therefore accessing the hard drive as the slowest link in the laptop and brakes.
Overheating, the processor goes into throttling - install a monitoring program (cputemp), change thermal paste, clean it from dust, check fans
Poor power - check the voltage on the power supply in idle mode and under load, change the power supply to check.
