Why do colorful stripes appear on the monitor?

There are the following solutions:

1. First try to plug the cable interface tightly to see if it solves the problem.

2. If it is a graphics card problem, you can shut down the computer and plug it in again to see if it can be resolved. If there is no black line after replacing the computer, it basically means that there is a problem with the graphics card memory. If it is within the warranty period, it will be sent to the manufacturer's repair station for free repair. If it is not under warranty, it can be sent to a nearby electronic city for repair. If the graphics card is relatively old, it is recommended not to repair it but to replace it with a new one.

3. Strengthen the heat dissipation inside the chassis and the use environment, such as regularly dusting the interior of the chassis, replacing the fans of the power supply, CPU, and graphics card. In the summer, turn on the air conditioner or fan indoors to ventilate and dissipate heat, and reduce playing large games. Game time etc.
