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

Intel HD 620GTX 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?
​//Edited the content to add model name.   ​
