I need advise on how to fix this issue, as I cannot install DOOM for instance, because its 60 GB, so the opportunity to freeze/crash is quite high - and after each incident I have to verify the game files via Steam because DOOM (or any other large game I want to play) won't start as the crash/freeze corrupted the files.

So something must be up with the way Steam downloads/installs the games. I have Windows 10 without any third party anti virus scanner, I'm only using Windows Defender and disabling it did not fix the problem. games via EAs Origin Platform (BF4 ~ 30GB, or Star Citizen (~30 GB) everything works fine - no crashes, no freezes. The weird thing is: When downloading other large files, i.e. disable all non-microsoft services (besides the steam client service - without this steam obviously won't start.) run chkdsk on the HDD where I install my Steam games on update/reinstall all third party drivers (graphics driver, network driver) DOOM, The Witcher 3) my PC frequently completely freezes (not a 5 second freeze or something like that, but a crash, and without blue screen or reboot, just complete standstill).
