Is the hardware in my Aspire 5 Acer Aspire 5 A517-51G-39NJ damaged ?

Hello,
I'm having serious problems with an Acer Aspire 5 A517-51G-39NJ that I'm supposed to repair.
The computer was purchased two years ago, it is no longer under warranty now, and its owner has used it very rarely.
At first, the system was very slow to boot (when there is almost no program installed by it) and BSODs were frequent.
The owner then took it to the store to have it repaired, and according to them they formatted the current Windows.
When I received the computer, I also noticed the slowness of the system and the very frequent BSODs, even for a basic task like watching a video: the errors indicated were of the type KERNEL_SECURITY_CHECK_FAILURE, MEMORY_MANAGEMENT, SYSTEM_THREAD_EXCEPTION_NOT_HANDLED...
Even when updating all the drivers and installing the latest Windows 10 updates, it was still unstable.
So I reinstalled Windows 10 on a USB stick using Windows 10 Media Creation Tool. On the installation menu, no problems were encountered.
However, after the first installation, when the installer rebooted the computer, and the ASUS logo was displayed with the load running in a loop and indications like "Device Preparation - X%", after a while, it was running in a loop on the same step, and then, BSOD.
Then if I tried to reboot the computer, I would get an error message saying that the system is corrupt and that I need to reinstall Windows 10 again.
I reinstalled, and this time I was able to use Windows 10 by creating an account on the computer and doing all the indicated steps. I re-installed the drivers, updated the system again, but I was still receiving BSODs, mainly MEMORY_MANAGEMENT, for the simple task like running Chrome (the computer has 8GO DDR4 though).
And by copying photos to the HDD from another USB key, another BSOD, this time SYSTEM_THREAD_EXCEPTION_NOT_HANDLED.
Here if I currently restart the computer, Windows on the unlock screen only has a blue background, and if I log in to the computer user, explorer.exe is totally corrupted. No icon on the desktop, no start menu, just empty loads and messages to close the process. I will try to SFC, DISM and CHKDSK the drive with a Windows 10 USB since ALT + F10 don't work.
Looking at the state of the hard disk before with Crystal Disk Info, I saw that the program indicated it in a correct state, which seems too right for a hard disk that has booted up very little and been used.
It's strange that even with a brand new Windows, these errors come back.
Do you think the HDD or RAM is damaged?
Thank you.

Original specs for this model are 4GB soldered RAM on the mainboard and one replaceable RAM socket. If it has 8GB RAM, you could first try to remove the 4GB replaceable RAM module to see if it boots up OK without the BSODs on the 4GB soldered RAM alone. That would help to rule in or rule out a replaceable RAM module as the issue. If not, we decide on what to test net. Jack E/NJ
