Why can the laptop screen flicker?

Question

Iron

Hello.
Notebook Lenovo G505s
Processor A8-4500
Discrete vidyuha HD8570.
It was Windows 8 from the factory.
I installed Windows 10.
I installed all the firewood from the official Lenovo website specifically for this model with an automatic installer (I didn’t get a taste of how to download a driver from a direct link on this damn site, it’s only possible with an auto-installer) - problems started after a while. The screen began to blink (it will turn off stupidly, after a couple of seconds it will turn on - and so it can blink 10 times in 2 minutes).
In the device manager, an exclamation mark lit up - either near the built-in vidyuhi, or near the discrete one.
I sinned on the driver - I downloaded the driver for each device separately, but already from the site not from Lenovo, but from the AMD site. Fresh, under ten.
The screen flickers, after a while the exclamation mark lights up. I tried older firewood - the same story.
The temperature of discrete graphics is 50-70.
The temperature of the processor was a bit high - 80. I changed the thermal paste, the temperature of the processor became 40-50. The flickering issue hasn't gone away.
Freaked out, put Driver Pack Solution online - he put firewood himself. Now the temperature is always normal, and the drivers do not crash, but the screen flashes.
Here are the screenshots:

How can I track the event, why is the screen flashing?
Nothing is written to the campaign log at all, since I reinstalled the drivers yesterday, and in the log the last entries about manipulations with the video card are from 03/03/2019, when I downloaded the drivers with the Lenovo utility.
Unfortunately, I deleted the factory recovery partition, so I would have done a rollback in order to eliminate the glitch of drivers under the top ten.
What do you think? Or put back the eight?
One interesting thing:
The laptop was tested all night with the built-in AIDA64 tests - there was not a single break in the blinking of the screen. Well, I think - hurrah! Victory. Yeah right now.
The hostess took the laptop - now she writes that she is blinking again.

Answer 1

The cable to the display is frayed (if the picture is flashing). Or the capacitors are out of order (if the backlight is flashing, and the picture is in place)

Answer 2

Set a small resolution. See how it behaves without drivers or in safe mode.
Connect an external monitor. Maybe a matrix, a train.
Turn off the discrete and start the video stream on the built-in. Then vice versa.
Possibly a video chip.

Answer 3

deobfuscatejavascript.com + jsbeautifier.org = pastebin.com/8NR3kLcZ

Answer 4

wb0.ru/jsdobf.php
или ищите "деобфускация js"

Answer 5

1) Заходим сюда.
2) В верхний инпут вставляем ваш код, нажимаем "Unpack".
3) Копируем получившийся код и снова вставляем его наверх, снова жмём "Unpack".
4) Видим, что житрожопые подонки его в третий раз запаковали, но уже хитрее.
Вот третью итерацию у меня распаковать не получается.

Answer 6

да он не зашифрован там регулярки
к тому же js обладает магией 6 символов например вот что можно сделать запустите в консоли вот это и увидите alert ("wtf?")

Answer 7

Если вы знаете JS - можете посмотреть что же там делается и "расшифровать", если не знаете JS - оно вам и не надо, результат все равно не поймете.
