Why are there green dots on screen NVIDIA suddenly?

Hey! So if those green dots just, kind of, start showing up on your screen all of a sudden, and you’re using an NVIDIA graphics card, there are a couple causes that could be behind it, you know. Like maybe the graphics driver is acting weird, or a recent driver update didn’t really install right. Or, the GPU could be overheating and then the visuals get those artifacts, dots , streaks, stuff like that. Another common thing is a display cable that’s loose or damaged, especially if you’re using an external monitor. And yeah, sometimes the monitor itself is the culprit.

Also, there are “GPU artifact” problems, which can point to failing graphics memory, meaning VRAM, or some other hardware issue with the graphics card.

A few quick tries you can do:

Try restarting your computer first.
Update the NVIDIA driver again, or reinstall it completely.
Check the GPU temperature while you game or run something heavy.
If you can, test with another monitor or swap the cable.
And if you take a screenshot, that detail matters. If the green dots show up in the screenshot, the GPU is probably the one causing it. If the screenshot looks normal, then the monitor or cable is more likely.

Finally, if the dots only appear during games or other graphics-heavy tasks, that usually leans more toward a driver problem or graphics card issue.
