Artifacts and graphical glitches: Sometimes, GPUs can display visual artifacts or glitches on the screen, such as flickering, distorted images, random colored pixels, or texture errors. This can occur due to faulty GPU memory, overheating, or outdated drivers.

Overheating and thermal throttling: GPUs generate a significant amount of heat during operation, and if the cooling system is inadequate or obstructed, the GPU can overheat. Overheating can lead to reduced performance, system instability, or even GPU damage. Some GPUs are designed to throttle their performance automatically to prevent overheating.

Driver problems: GPU drivers act as a bridge between the GPU and the operating system, enabling communication and providing necessary instructions for rendering graphics. Outdated or incompatible drivers can cause issues such as crashes, system freezes, or poor performance. Updating to the latest drivers or rolling back to a stable version can often resolve driver-related problems.

System crashes and blue screens of death (BSOD): A malfunctioning GPU or incompatible drivers can cause system crashes or trigger the infamous BSOD on Windows systems. These crashes can occur during gameplay, graphic-intensive tasks, or even during regular usage.

GPU fan failure: The fans on the GPU are crucial for cooling and preventing overheating. If the GPU fans fail or stop functioning properly, it can lead to increased temperatures and potential GPU damage. This issue may require replacing the GPU fan or the entire GPU card.

GPU not detected or recognized: In some cases, the GPU may not be detected or recognized by the system. This can happen due to driver issues, improper installation, or hardware conflicts. Troubleshooting steps such as reseating the GPU, updating drivers, or checking BIOS settings may be necessary to resolve this problem.

GPU compatibility issues: GPUs have specific hardware requirements and may not be compatible with all systems or motherboards. Compatibility issues can result in the GPU not working correctly or not functioning at all.
