The processor freezes at 0.79 Hz (Core i7-8750H 2.20 GHz)

Hello, something out of the ordinary happened.

In general, there is a ROG Strix GL503ge laptop, Intel Core i7-8750H processor 2.20 GHz
Bought for work (compression and distillation, video processing). But the game holds very well. Any.
The video processes at 80-120 fps.

Yesterday, the frequency dropped to 7-8fps. 5 different reinstallations of windows did not solve the problem. Even put it from scratch on an empty disk.

They reset the BIOS, overclocking was not used. zero.
Updated BIOS. Also zero.

Bought from the online store Poland. Warranty in another city. But service is possible only in Poland.

Who can help explain what happened to him and how to solve the problem, what other options can you try?

I attach screenshots. The photo shows that the percent for a long time is loaded at 0.79 GHz. at the same time, a load was started (video driving), some game. More than 0.79 does not rise. This is the ceiling.

Separately, I add the laptop did not fall, there was no network overvoltage. Powered by the network on the table. The temperature on the screenshots is also calm.

Writes 0.79 memory and its current load to the CPU in the task manager.
The video itself is processed for 4 hours instead of 30 minutes. During this time, a CPU of more than 0.79 Hz does not go. Once again I ask you for help and solution options.

Is the battery full and working properly? Some laptops limit themselves if the battery is faulty.

Download ThrottleStop and see if you can fix it through there?

If not, try setting power targets to 100% in power management. Also, set it all to performance in Nvidia Control Panel. (I assume you have Nvidia GPU)

You could always format the laptop see if that helps.
