less processor performance Intel Core i5-7200U - Intel HD 620 less performance 2D graphics

[Serhio]

Hi
I have a laptop E5-575G-53V2
https://www.acer.com/ac/ru/RU/content/support-product/6737?b=1
Processor
Intel Core i5-7200U @ 2.50GHz

Intel HD 620

GTX 950M
There are two moments that cannot be eliminated.
After reinstalling, the OS has a question mark device - PCI memory controller.
ID
PCI\VEN_8086&DEV_9D20&SUBSYS_00000000&REV_21
(has not an exclamation point, but a question mark)
The description says:
"This device is not currently connected to your computer. (Code 45)
To resolve this issue, connect your device to your computer. "
If I delete a device, it appears with an exclamation point.
Installed all the drivers of the manufacturer and also DCH driver through Intel Support Assistant.

Also, after reinstall OS, passmark test readings fell
15% less processor performance.
50 percent less performance 2D graphics.
Something works wrong. But it's not clear what. He turned to TS Acer, but they said that all the drivers were laid out and there were no problems on their part.
Can someone help and clarify the situation?

- Was it working fine before the reinstallation of the OS?

There were errors in the OS logs. Sometimes there were crashes in the games, a blue screen. Now I have increased the RAM to 16 GB and so far there have been no sorties.

- Have you checked the issue with Microsoft?

No. Microsoft does not provide technical advice. advise only on product activation and updates. So the TP specialist told me.

- Did you use a fresh copy of Windows to perform the reinstallation?

I used a fresh copy of Windows to reinstall.
Iak tried to clone OS on another disk and reset by resetting to its original state. The result is the same performance also dropped after the reset.

- Screenshots of the issues.

This is useless information. Acer didn't help me. They said that all the drivers are posted on the site. And the fact that they are old does not bother them.
I was hoping for your help.
