GPU artifacting is visual corruption caused by errors in the calculations your graphics card is doing, such as random lines, dots, stray symbols, or wrongly drawn textures. Start by cleaning up drivers, resetting any overclock, and checking temperatures. If it survives clean drivers, stock clocks, and normal temperatures, the card is likely failing.
- Artifacting is corruption rendered by the GPU itself.
- A screenshot shows whether it’s the card or the cable.
- Drivers, overclocks, and heat are the fixable causes.
- If all three are ruled out, the card is likely failing.
What GPU Artifacting Looks Like
- Random lines across the screen, often colored and flickering
- Stray symbols scattered over the image, sometimes called space invaders
- Dots or speckles
- Textures or models drawn wrongly, stretched, or made of the wrong material
- Blocks of the image shifted to the wrong place on screen
The common thread is that the corruption is drawn into the frame by the card, not lost on the way to the screen.
Is It the GPU or the Cable?
Take a screenshot. It’s the quickest test, because a screenshot captures what the GPU rendered, before any cable is involved.
| What you see | Likely cause |
|---|---|
| Corruption in the game and in screenshots | The GPU (artifacting) |
| Corruption on screen, but clean screenshots | Cable, port, or monitor |
| Flickering, snow, or cut-outs | Cable or connection |
| Corruption in the BIOS, before Windows loads | Hardware fault |
| Corruption in one game only | The game or the driver |
What Causes GPU Artifacting
- Overheating from dust, failed fans, or poor thermal paste contact
- An unstable overclock, especially on the memory
- Outdated or corrupted drivers
- A hardware fault, such as a failing GPU or damaged VRAM
Heat is worth ruling out first. Check what GPU temperature is too high against your own numbers under load.
How to Fix GPU Artifacting
- Take a screenshot to confirm the problem is the GPU, not the cable.
- Do a clean driver install. Remove the old driver completely, then install the latest one from Nvidia or AMD. Our guide to uninstalling GPU drivers shows how.
- Undo any overclock. Return core and memory clocks to stock in a tool like MSI Afterburner, then test in a demanding game.
- Check temperatures under load, clear dust from the card and case, and confirm the fans are spinning.
- Reseat the card and its power cables.
- Lower in-game settings such as textures and shadows to see if the corruption goes away.
Bottom line: if clean drivers, stock clocks, and normal temperatures still leave you with corruption, NZXT’s guide is blunt: the card is very likely failing, and there is no software fix for a GPU producing bad calculations.
When the Card Is Failing
Check your warranty first and contact the maker with photos or video of the problem. Outside warranty, see whether a GPU can be repaired, or how long you can reasonably expect one to last in how long GPUs last. If you want to reproduce the fault on purpose, run a GPU stress test and watch for glitches.
Frequently Asked Questions
Can GPU artifacting fix itself?
If it’s caused by drivers, an overclock, or overheating, yes, once you fix the cause. Hardware degradation won’t improve, and usually gets worse.
Does artifacting mean my GPU is dying?
Often, but not always. Rule out drivers, overclocks, and temperatures first. Corruption in the BIOS, before Windows loads, points to a hardware fault.
Can overheating cause artifacting?
Yes. A card running past its thermal limits can produce visual errors. Check temperatures under load and clear dust.
Will a new cable fix artifacting?
No. The corruption happens before the signal reaches the cable. A new cable fixes flickering and dropouts, which are different symptoms.
