You sound like you have a messed-up setup, especially with the ROG Gaming Center software. Lightbar, Fan issues stem from there.
It reboots because the fans wont speed up and you boil the laptop with stress tests.
Have you installed the BIOS update to 306 and the "keyboard fix" update?
Gestures breaking when waking from sleep (such as 2 finger scrolling) is a known problem.
Do you have USB input devices attached, like a mouse? Those can wake up a sleeping, closed laptop if the UEFI/BIOS setting says so
Especially if you set your laptop to keep running when closed, maybe to run it with a bigger, external monitor
Do you have other screens attached via HDMI? Sometimes the internal screen stays switched off for me if i had one connected, reboot or reconnecting the screen then opening the laptop "fixes" the switched off internal one.
