GPU or integrated graphics card malfunction causing graphical artifacts or black screens
My PC is experiencing severe graphical issues, with distorted screen artifacts, flickering lines, and sudden black screens that occur randomly during both gaming and regular desktop use. I have already tried updating my GPU drivers, reseating the graphics card, and testing different monitors, but the problem persists, suggesting either a failing dedicated GPU or an issue with the integrated graphics.

A quick recommendation to improve security and reduce unexpected issues in Windows 11 is enabling SmartScreen.
You can turn it on via: Settings → Privacy & Security → Windows Security → App & Browser Control.
SmartScreen helps block malicious downloads and suspicious websites. It’s a very effective protection layer, especially for users who might accidentally install unsafe software that can lead to crashes, graphical artifacts, or instability.
