Windows 10. When installing software, broken files are constantly detected, what could be the reason?

Question

Windows

Guys who are well versed in a PC, there are always broken files when installing any software, and it doesn’t matter if it’s an old HDD, or a new SSD drive that is less than a couple of weeks old, maybe this is due to incorrect operation of RAM?
Windows was installed from a flash drive (normal, not broken, not drowned);
The Windows installer was downloaded from the official site;
SSD as above is new;
No bad HDD/SSD sectors detected (console);
When installing Windows, there were constant problems and errors associated mainly with broken installer files. (I solved the problem by reducing the memory section for the system)
I don’t take them into account due to the fact that when I put Windows on the laptop everything was fine.
Drivers are installed, used DriverPack Solution updated the same drivers manually;
