Question Artefacts appeared on my screen, could my monitor or GPU be at fault ?

[Mlit]

This morning I turned my pc on and did my normal routine and noticed a lot of artefacts appearing on the screen. On the text it's small pixels obscuring some of the letters and larger rectangles appear at the bottom of the screen and on the task bar. Print Screen will capture the letter pixels but the rectangles don't show up. The rectangles also disappear or rearrange when I move the pointer so I can snipping tool them. The mouse pointer isn't obscured by the artefects. I can run the pointer over them easily. Is my monitor or gpu at fault here? The artefacts are showing up while running Firefox and over the start bar, I ran Word but nothing seemed to be happening there. Don't have time this morning to run any other checks as I'm pressed for time. Anyone know what could be happening. I'm running an Asus TUF 3080 10GB and a TUF VG27AQL1A monitor

Please include an image of what you're seeing.

As for your issue, if you migrate the panel to another system and see the issue persist, then it's a panel issue. If a donor panel on your existing platform is hooked up and yet exhibits the issue, then the GPU might very well be at fault.

Open up GPU-Z and also pass on a screenshot of what you see. A bad PSU can cause your GPU to conk out, as can be the case of letting the GPU run in a high temp environment for long periods.

PSU? That's interesting, I'd never considered that. My current one is a thermal take GF3 1650, very new but only keep it on default fan speed. However I'd only just turned the pc on when the artefacting happened.

Havn't had it happen again, been powered on less than ten minutes at time of typing.

Before switching monitors around I propose switching my 3080 out for an old 1070 I keep laying around, never had any issues at all with that one. If the issue still happens, it could point to the monitor.

Would there be a reason for why I could move my pointer over the top of an artefacted rectangle rather than the pointer being distorted as well?
