If you have an AMD processor system, the GPU is the main component that would help turn on the system. But if the graphic card dies, your system will not turn on. However, if the failed graphics card is an Intel processor, your system will turn on, but it won’t run any software or application that uses a graphics card. There would be evident off-color pixelation, screen flickers, random artifacts, and screen glitches hamper the user interface.  If you think your graphics card might be on the way out, there are a few things you can do to test it and prolong its life. Here's what you need to know about what happens if a graphics card dies. One of the first signs that a graphics card is starting to fail is stability issues. You might experience crashes, blue screens, or system freezes. Testing your graphics card for problems is good if you see any of these symptoms. There are a few ways to do this. You can run a diagnostic program like FurMark or MSI Kombustor to test your graphics card's performance and stability. You can also check your system's event logs for any errors related to your graphics card.
