Explanation
Graphical artifacts - such as screen tearing, random pixels, or corrupted textures - that appear only after the system has been running for a while are a classic symptom of thermal throttling or overheating in the GPU. Heat causes instability in the graphics processor, resulting in rendering errors. Since drivers and OS updates have already been eliminated as causes, a hardware thermal issue is the next logical culprit. Defective cabling would cause artifacts immediately, not only after prolonged use. An outdated BIOS or incorrect GPU firmware would typically cause issues at startup or consistently, not progressively after warm-up.
