If we turn on the computer and find that the computer is in a black screen state, the desktop does not display, and only one mouse is lying alone, what will you do?
Start black screen only mouse solution one
Desktop 1. After the computer is turned on and enters the system (that is, after the startup screen appears), the screen is black. At this time, the computer has no desktop (no taskbar, no wallpaper), and the entire computer screen has only one mouse.
2. This may be because the virus modifies the registry options or destroys explorer.exe, which causes explorer.exe (our daily operation interface) to fail to load normally after entering the system, and then a black screen appears.
3. Win7 system is not activated. The desktop icon and taskbar are all there. Only the desktop wallpaper is black. The next activation software. There are many such software on the Internet. Just activate it. Make sure that after activation, changes to wallpaper and themes are normal.
4. In some cases, for example, after power on and entering the system, the taskbar is still there, but there is no icon on the desktop. This is not a problem. It is a problem of our settings. Right click on the desktop -- view, and check the icon in front of the desktop.

Desktop computer 1. Restart the computer, press F8 to enter the Startup menu, select "use the last correct configuration" to start the computer, and wait a moment to see if the black screen only mouse fault is eliminated.

3. You can choose to go to the "startup" tab, remove the unnecessary check before starting the program, so as to prevent the software of some startup items from conflicting with each other, and then restart the computer.
4. If it still doesn't work, you can choose "diagnostic startup - only load basic device drivers and services" under "general", and then restart the computer, then it can start normally.
5. After entering the system normally, check whether the C disk of the computer system is full, clean up the garbage of the C disk, and uninstall the unnecessary software and programs.
Start black screen only mouse solution 3
Desktop computer 1. Poor contact between hardware, or hardware failure. Related hardware involves memory, graphics card, CPU, motherboard, power supply, etc. Power on the computer first through the power supply, then by the motherboard BIOS boot self-test, and then through the CPU, memory, video card and so on.
2. This process is reflected in the screen called self check, first through the BIOS information of the video card, then the main board information, then memory, hard disk, optical drive, etc. If there's a problem with one of these steps, the computer can't start normally, or even the screen is black.
3. First, confirm whether the external connection and internal connection are connected smoothly. External connection includes display, host power supply, etc. internal connection includes host power supply and host power interface.
4. Because the computer's video card and memory are used for a long time, they have long-term contact with the dust in the air, resulting in the formation of an oxide layer on the gold finger, resulting in poor contact.
5. Wipe the gold finger back and forth with cotton and alcohol, and then insert it back after drying. In addition, observe whether the CPU works normally, turn on the CPU for about half a minute, and touch the heat sink of the CPU fan with your hand to see whether there is temperature.
6. With temperature, the possibility of CPU failure can be basically eliminated. If there is no temperature, clean up the CPU socket to make sure it is in place. There is no temperature after that, so your CPU can be upgraded.
