Hello everyone, Lin Fei to answer the above questions, the computer boot does not display the desktop icon, boot desktop icon does not show many people do not know, now let's take a look!

The utilization rate of computers is very high now. With the advent of the information age, computers have long become an indispensable part of life. But sometimes the computer is easy to break down in the process of use. So, how to deal with the situation where only the desktop background is displayed and there are no programs or applications when the computer is turned on? Let's have a look.

1. What if the desktop icon is not displayed after the computer is turned on?

Restore explorer.exe, and you can solve it (just copy and restore one with the command, and then enable it). The specific operation methods are as follows:

1. Press ctrl+alt+del to invoke the task manager and create a new task.

two。 Enter the following command (note the spaces) cmd/k copy c: Windows System32 DLLCache explorer.exe c: Windows.

3. Then run the command again: explorer.

It's done. There is a desktop icon!

Second, after the computer is turned on, what if the desktop is black?

1. Check whether the computer parts are firmly inserted.

First check whether the display cable is firmly plugged into the host interface, and then check whether the contact between the video card and the motherboard Iram O slot is good. If necessary, remove the video card and reinsert it to make sure it is in place and in good contact.

two。 Confirm that the monitor is not damaged.

If the monitor and video card are securely installed, try another known good monitor. If the screen is no longer dark, the reason is that the monitor may be damaged.

3. Confirm if there is a problem with the fan.

If the monitor is not damaged, further check to see if the CPU fan is running. For example, you can use a multimeter to measure whether the normal voltage output is 12V or 15V. If it's not normal, you can try another power supply.

4. Check the CPU, video card, and memory module.

If the black screen still appears, remove all components except the CPU, video card, and memory module, and then power on the computer. If there is a memory failure, there should be an alarm. If it is not a memory problem, please change to a normal CPU and power on to retest. If there is still a black screen, only one motherboard can be replaced, and the problem should also appear on the motherboard.

In addition to the black screen phenomenon caused by hardware reasons, there are three "soft" reasons that may lead to "black screen".

1. The hardware acceleration setting is too high.

Hardware acceleration can make software that has to deal with a large number of graphics run more smoothly, but if the computer hardware acceleration setting is too high, it may lead to "black screen" phenomenon. To solve the "black screen" problem, please try to reduce hardware acceleration.

Click the Windows start menu, click the control panel, and then double-click to display.

(2) Select the troubleshooting tab, and under hardware acceleration, gradually drag the slider from all to close to none.

(3) Click OK button.

two。 Disable 3D acceleration or upgrade graphics drivers.

If Windows is already configured with 3D acceleration, but the video card does not support this feature, a "black screen" failure may occur when running games or multimedia programs.

Click "start", then click "run", then type "dxdiag" in the "Open" box and press enter.

(2) Select the "Display" tab and click the "Test Direct 3D" button under "DirectX Function" to get the correct Direct 3D function.

(3) if there is no rotating cube on the screen, the graphics card does not support 3D acceleration. At this point, click the "disable" button after "Direct 3D acceleration" to disable this feature. If your graphics card does not support 3D acceleration, in addition to disabling this feature, you can also contact the graphics card manufacturer to update the driver to support DirectX 3D acceleration.

3. The video card driver is incompatible with the video card.

The DirectX installer may incorrectly detect the video card and install drivers that do not drive properly. Make sure you are using the correct video driver.

(1) Click start, click Control Panel, and then double-click the system.

(2) Select the "hardware" tab, click the "device Manager" button, and then click "" before "display Card" or "display Adapter", then right-click the display adapter below it, and then click the "Properties" button.

(3) Select the "drivers" tab and click the "driver details" button to display the video card driver used. If you are using a driver that is not compatible with the video card, click the Update driver button on the drivers tab, and then follow the on-screen instructions to install the new video card.

Third, what if the computer does not display the desktop but only the mouse after the computer is turned on

Press the Ctrl Alt delete key combination, select "start Task Manager", pull up "New Task (run)" under "File", type explorer.exe in it, and then click OK. After entering the system, use 360 security guards to carry out "system repair", antivirus and so on.

4. The mouse cannot be moved after the computer is turned on

1. Turn the mouse over and look at the indicator light.

2, not bright may be a problem with the mouse, we first try to reseat the connection cable between the mouse and the host computer.

3. There are two kinds of connectors for computer and mainframe, which are U port and P port respectively.

4. U mouth does not say much, it is not difficult, P mouth should pay attention to the needle inside do not bend, plug out.

5. If the problem is solved and the pointer can be moved after reseating the cable, it means that there is no problem with the mouse, and the connection is not real. If it is still not lit, it means that the mouse is broken. Let's analyze another situation, the mouse is bright, and we have to consider whether it is a computer program.

6, press the keyboard, call up the task manager, if there is a response, it means that there is no problem with the system, if there is no response, it means that there is a problem with the system, we can press the host restart key to restart the computer to try, restart does not work, then we have to reinstall the computer program.

In general, the above emergencies in the computer are caused by one of these reasons. Mastering the causes and maintenance methods of some of the faults mentioned in this article can help you solve the problem quickly and effectively.

At the end of this article, I hope it will be helpful to you.
