... When I do it, I will definitely make a restore point before installing so I could return to the working system if needed.
Getting everything going correctly on a nice new system like that is certainly possible, with Armoury Crate I mean. Not easy though. I have actually written a thread where I talk about the first Armoury Crate install. This thread was written some months ago and the situation hasn't really changed. I am not sure if you are asking for help. Let me know.
"Not easy though".
Therein lies the problem. I'm a vanilla user technically. I don't mess with individual timings, clock speeds, etc. I shouldn't have to search system folders/sub folders to delete small parts of code that render my PC potentially useless in effect. Deleting aspects of any program is just as dangerous as messing with the RAM/CPU speeds if you don't know what you're doing, which I mostly don't. I just assuming that someone at ASUS knows what's wrong and with future updates they may fix this, so that I might just enjoy my rig like I have always before AC became a thing. Hoping anyways.
The parts I would suggest have more to do with what drivers and software to install in what order. It should not be necessary to do any manual deleting or tweaking of things on a new system. In other words, if you can update/flash a bios and spend a little time getting all the latest drivers installed, and then patiently install software one a time and make sure its working before going on to the next, you can get there. Before doing any of that a full memory stability test with memtest86 is something I wouldn't skip either.
That's what led me to where I am. I've installed one program after another, slowly and deliberately, both before and after re-installing Windows twice, and AC still seems to be the root of all my problems. It upends the entire system and creates chaos whenever it's installed. My whole point is that I shouldn't have to sacrifice any fully operating programs to find a fine balance of function from a software that ASUS makes semi-mandatory with their own hardware. It just seems ridiculous. I suspect that AC is carrying a lot of excess driver baggage from earlier versions of Windows. They'll get around to sorting it out, just not in a time frame that makes me happy.
I'm too invested in to this rig, so I'll give them more time. Now, without AC installed the system seems stable. No crashes since the last re-install. decent BOOT-REBOOT times, and all games running smoothly.
