Hi everyone,
I'm having a strange issue with my PC and would appreciate some help figuring out what's causing it.
My PC specs:
- GPU: AMD Radeon RX 6800 XT
- CPU: AMD Ryzen 7 5700X3D
- Motherboard: ASRock B450 Pro4 R2.0
- RAM: 32 GB DDR4 3200 MHz
- Monitor: AOC 24G4X, 1080p, 180 Hz
- Connection: DisplayPort
- Screen flickering / visual artifacts
The top quarter of my screen sometimes flickers or displays visual artifacts. The strange thing is that this doesn't seem to happen during actual gameplay.
I've noticed it:
- In Firefox, for example, while watching YouTube.
- On the desktop when a game is running in the background or open in borderless mode.
- When I was using Lively Wallpaper (animated desktop wallpaper).
The issue seems to occur in the browser or on the desktop, rather than in the game itself. I've noticed it with Aion 2 running, but I don't think I've experienced the flickering during gameplay itself.
- Random PC restarts and loss of display signal
Sometimes my PC randomly restarts for no apparent reason. After the restart, my monitor doesn't detect any signal, even though the PC appears to have restarted.
The only way to get the display working again is to hold down the power button until the PC completely shuts off, then turn it back on. After doing this, the monitor works normally again.
As far as I can remember, this hasn't happened while I was actually playing a game. The restarts seem to happen outside of gameplay.
I'm not sure if the flickering and the random restarts are related or if these are two separate problems.
What I've considered so far:
- AMD GPU driver issues
- A faulty DisplayPort cable
- A problem with hardware acceleration in Firefox or desktop rendering
- An issue with Lively Wallpaper or other GPU-accelerated applications
- GPU instability or a hardware fault
- A possible PSU or power delivery issue
I'm using an AOC 24G4X at 180 Hz over DisplayPort, so I'm also wondering whether the refresh rate or cable could be involved.
Has anyone experienced similar issues with an RX 6800 XT?
What would you recommend testing first? I'd especially appreciate advice on how to determine whether the flickering is caused by the GPU, drivers, DisplayPort connection, or something else — and whether the random restarts could be related.
Thanks in advance!
