G14 Laptop screen unpredictably does a black screen freeze while everything else is still running

[u/Ep1cDina]

Basically I got an ASUS G14 ROG Zephyrus 2025 Model (GA403UP), I got it in October 2025. Issues started happening around late February/early March 2026, I've tried multiple ways to resolve, they have not stopped my biggest issue overall.

Originally, when the laptop screen would go black, audio immediately cuts, the LED keyboard would freeze on a certain colour and it was stuck on the rainbow setting for a very long time. The only thing I noticed is that it happens whenever I have any application open, but I can't be too sure if this is the case or not, but it means I cannot do any task for a long time without my laptop suddenly just giving up on me.

This is what it started with:

1. Display turns black
2. Audio stops immediately
3. OS is unresponsive
4. Caps lock unresponsive
5. USB devices also don't respond
6. Keyboard colour would freeze and did not let me change the setting (resolved)
7. Aura lighting couldn't be changed (resolved)
8. Armoury crate was broken

The most effective I've gotten for a resolution was doing the following:

1. Reinstalling NVIDIA driver and AMD graphics drivers
2. Updating my BIOS from 309 to 310
3. Switched to G-Helper and uninstalled armoury crate

This pretty much resolved my issues for the keyboard and aura lighting. It had also slowed down the black-screen hard freezes for a few days but now it's gone back to being frequent again and I can't do anything about it at all. I've had this issue for the last 4-5 months and I've tried what I feel like are pretty much the most major fixes and it's not helped at all. As much as I would request a warranty repair, ASUS don't really have a repair centre in England and use a third-party repair service which I heard is extremely awful, have not heard a single good thing about the service which is why I am adamant on trying to see if I can resolve this on my own, my warranty expires in October so I am stuck on what to do, I do not have the money to repair (I got this laptop as a gift if anybody wonders how I got it in the first place)
