The graphics card can't keep up with the running speed of the machine, which causes the cpu to shut down automatically when the temperature is too high. Turning off the cpu as soon as it reaches 70 degrees is to protect the cpu from being burned. In the long run, the menu will be terrible. It is recommended to replace the cpu with a high-power fan and the graphics card with a larger memory. The current graphics card is at least 5 12. Please change it to1g. Changed the graphics card to solve the card problem!
