The graphics processing unit in a computer handles tasks related to displaying visuals and can be part of a dedicated card or integrated with the motherboard. Like any other computer component, the GPU is subjected to strain when under heavy loads or overclocked. Indications that a GPU is reaching the end of its lifespan usually include visual anomalies, instability and poor performance along with increased fan noise. Since these issues can also be caused by other factors, it is important to test the computer with a different GPU to confirm that the problems are not caused by other faulty hardware or driver issues.
