Turn on GAT5 to play for a while and then it won't work! The CPU frequency is high! What hardware do you need to change? It is best to install hardware to solve it! Come professionally!

This is a problem with the graphics card. Because your graphics card performance can't keep up, you need the help of CPU to run. So the temperature and occupancy rate of your u have gone up, and it will be much better if you change your graphics card. However, in view of the performance of your U, a graphics card of HD7750 or R7 260 level is enough. No matter how high-grade the graphics card is, your U can't play all the functions of the graphics card.
