A bad GPU is when you see the 'Failed to initialize graphics device' or 'Display driver stopped responding and has successfully recovered' error after installing a new card on your computer. If this happens, turn off the computer and repeat steps 3-6 in the troubleshooting tutorial below. Laptops have a built-in GPU that will work for most internal uses of your computer. If you are experiencing errors with games or other programs, it might be due to a poorly optimized game (not supported by this GPU). This can lead to long loading screens, poor frame rates, black screens, etc.
