LU Master graphics card test black screen reason

The main causes of black screen are as follows:

1. Video equipment connection is not normal or damaged;

2. Bad memory contact (the machine will send an alarm) caused by the inability to boot;

3. Graphics driver Conflict or exception (this situation can normally boot in the system when the black screen);

4.CPU, graphics card overheating;

5. Abnormal resolution;

Workaround:

First, the black screen is not necessarily due to master Lu, you can try to reboot, check the hardware is operating normally! If not, please check the video device (video card, monitor) connection, reseat the memory, until the computer can boot normally.

Second, if it is Master Lu after the black screen, then master to install/update what graphics drivers, do not update or install. Because your system inside the drive is and your system and hardware is a match, an update, a lot of do not match, it is possible to black screen, blue screen, resolution not to go back to such issues, so installed problems, uninstall is not enough to reinstall the system.
