Hi everyone!
I want to share my own experience with this issue.
Two weeks ago, I bought an Asus Rog Strix G733PYV RTX 4090 machine for $4200. The problem started on the second day, where it would randomly restart. I began monitoring the temperature of the machine in Armoury Crate, but it wasn't under heavy use at all, and it even restarted while idle.
Then I started browsing Reddit and the Asus forums, where they suggested that the issue might be with Armoury Crate, and recommended using GHelper instead. I installed it, but it bothered me that I had to resort to such solutions on a two-day-old machine, especially one this expensive, so I contacted Asus Support. They advised me not to use GHelper because it's not an official program, which I completely understood. They sent me an installer for Armoury Crate and Aura Creator, which was indeed different from the one available on the Microsoft Store.
I tested the machine all day and thought I had solved the problem, but unfortunately, it restarted again. At this point, I felt a bit discouraged and was about to return the machine, but I decided to search online one last time. That's when I saw someone suggesting turning off Fast Boot.
Go to: Settings -> Control Panel -> Hardware and Sound -> Power Options -> On the left side, choose "What the power buttons do" -> In Shutdown settings, uncheck "Turn off fast startup."
Additionally, I disabled the Fast Boot option in the BIOS as well. I've been testing it for a week now, and no issues have surfaced. It's very likely that this was the problem.
I hope this helps someone, as I only found the solution by a stroke of luck.
Happy gaming!
