What is the reason for the computer screen?

1. Check whether the power supply is normal and stable;

2. Has the machine been upgraded in memory? Unplug the memory and wipe the golden finger of the memory with alcohol and rubber.

3. The driver is abnormal. It is suggested to delete the original driver and download the latest driver in safe mode.

4, replace the pure version of the system and try to see if it can solve the problem;

5. If the conditions permit, confirm the external monitor to see if the external screen is broken. If the external display is normal, it can be judged that there is a high possibility of screen failure, and it is recommended to conduct a specific after-sales test.

6. If the machine is overheated, it will also cause the screen to appear, which can clean the fan and reduce the working temperature of CPU.

7. Adjust the display angle of the screen to see if the fault has changed or returned to normal. If you can, you can use it temporarily, and wait for the idle time to contact the service station for further detection to see if there is the possibility of improper screen wiring.

if it is invalid, please also go to the after-sales specific test.
