When there are many players, the game server may be overloaded, resulting in a black screen.
Enter the game black screen
1. Before entering the game, change the screen swiping rate of the graphics card to 60 Hz, and then change the screen resolution to the maximum, but the effect is not very obvious.
2. After the screen is black, press the 'o' key and then press ESC to change the resolution of the game to the minimum. This method is easier to use.

I. check whether the computer components are firmly inserted. First, check whether the monitor cable is firmly and reliably inserted into the host interface, and then check whether the contact between the graphics card and the motherboard I / O slot is good. If necessary, please remove the graphics card and re insert it to ensure that the security card is inserted in place and in good contact.
II. Confirm whether the monitor is damaged. If the monitor and graphics card are firmly installed, please try another monitor that is confirmed to be normal. If the screen is no longer black, the reason is that the display may be damaged.
III. confirm whether there is a problem with the fan. If the display is not damaged, please further check whether the CPU fan is running. In case of operation, use a multimeter to measure whether the voltage output is normal to ± 12V and ± 15V. If it is abnormal, change a power supply for a try.
IV. check the CPU, graphics card and memory module. If there is still a black screen, you can use the "replacement method". The method is to replace all the CPU, graphics card and memory module with one that is sure to be normal, and then power up and start the computer. If there is a memory failure, there should be an alarm sound. If it is not due to memory, change a normal CPU and start it again for detection. If there is still a black screen, you can only change one motherboard, and the problem should also appear on the motherboard. In this way, you can eliminate it again and again until you find the cause of the fault!
