Why is there no sound on the computer, and the mouse can t move?

There is no sound on the computer, the most common is the driver problem What should I do if the computer has no sound (generally related to the sound card driver)? What should I do if there is no sound control icon in the lower right corner (generally related to multi-** management driver)? I'll help you drive the installation method, it's absolutely easy to use:

1.**The latest version of the Driver Wizard B1 or B2 2After installation--Driver Update--Multi** Management Driver (or Sound Card Driver), etc., there will be an update, which is the driver management software, and those with an exclamation mark mean that they are not installed.

Update, 20 minutes to get it (open the driver update project, see those that can be updated or not installed, click on the back and install it) 3After installation, uninstall Driver Wizard 4When used properly, Personality Guarantee 5

The second step is special instructions:If it shows no sound card driver or multi** management driver update,You can uninstall the original driver first'Uninstall it in my computer properties-hardware-device manager,Or you can also do it in the driver wizard,Then try there will be a driver update If it doesn't work,It's hardware reasons,Or external speaker equipment problems can only be repaired。

First, first confirm that the hardware is fine. If the speaker is fine, the sound card is fine, and if you've tested it on other machines and it's really good, then you can read on. 2. Make sure all the cables are exactly right.

Then power on the speaker and turn on the volume switch. 3. Install the driver of the sound card correctly, if it is an onboard sound card, it is best to install the driver provided on the driver disk of the motherboard. (Actually, the computer doesn't make a sound, and many times it's because the sound card is not driven correctly.)

In general, after the sound card driver is installed, there will be a small speaker icon in the taskbar in the lower right corner. Fourth, if you are sure that the driver is installed correctly, then take a look at the volume settings in the computer. Here's how:

Double-click the speaker icon in the taskbar to see if the volume is turned off to the minimum or muted in the Volume Control and Waveform dialog box that pops up. If these two options are not available in the dialog box, click on the "Options" menu - select "Properties" - select "Volume Control" and "Waveform" in the "Show Volume Controls" and then set them correctly. Note:

Step 4 can only be set up after the driver for the sound card has been installed correctly. Special reminder: In fact, many times, the reason why the computer does not work properly is a small fault, soft failure, careful analysis, many times can easily solve the problem.

Because your computer is stuck looking.

Open the task manager, use the tab key to switch to the following hardware options, and then use the down arrow on the keyboard, move to "Mouse Nian Sell and Other Pointer Devices" and press the enter key to see if the driver is normal, if there is an exclamation mark in the driver, it means that there is a problem with the mouse driver and you need to install the driver to solve it. Installing a mouse drive posture is generally relatively simple, as long as you install a driver wizard or drive life and other tools in the computer, you can detect and install faulty hardware drivers. If there is nothing wrong with the driver, it may also be a mouse malfunction, the best way is to plug it into another computer or plug it into your own computer to see if it is useful.

The keys of the mouse are micro buttons, and the plastic handle of the button is a small metal disc like an inverted pot, and your situation may be caused by the fact that the disc is not reset or cracked after being pressed, you will pull the plastic handle of the button up to see if it can be reset, if not, change it.

1: The spring plate is pressed, whether it is double-clicked is sometimes not sensitive, it is recommended to check the spring situation, let it reset or change the spring.

2: The button of the mouse is a miniature button, the plastic handle of the button is a small metal disc like an inverted pot, this situation may be caused by the disc being pressed without reset or cracking, pull the plastic handle of the button up to see if it can be reset, if not, just change it.

Downstairs, we call it Micro Motion. Let's see if you're stuck with something.

You have the ability to change the micro-touch keys!

A silent mouse is a mouse that does not tick when clicking, and it is not completely silent, and if you listen carefully, you can still hear some subtle sounds.

Here's how a silent mouse works:

The sound grinding mouse will make a clicking sound because of the structural design of the shrapnel inside the mouse, when the click action occurs, the shrapnel in contact with each other will make a sound. The silent mouse button silent principle, is to change the traditional sound mouse internal shrapnel design, with light through the infrared sensing button action, when the mouse button is pressed, the infrared is cut off, feedback this information to the microprogram controller, this process is almost silent, will not produce the ordinary sound stupid beam wide mouse click, greatly reducing people's night work for fear of affecting others' troubles.

Troubleshoot the computer that won't turn on and the screen is black.

Many times we will encounter the phenomenon that after pressing the computer boot button, the computer cannot be started, and there is no POST or enter the operating system, which often makes the user unable to deal with and affect the normal use. Here, we make a brief analysis of common fault phenomena, analysis and solutions, hoping to help users who encounter such problems.

There is no reaction after pressing the power button.

Fault phenomenon: After powering on, the screen does not have any display, and no "dripping" sound of the motherboard speaker is heard.

Fault analysis: The internal BIOS data of the COMS chip of the motherboard is damaged by CIH virus or static electricity, etc., and cannot be read, and the system cannot complete the self-test when it starts, so it cannot be started.

Known solution: Contact the motherboard manufacturer to replace the COMS chip with a new one or find the BIOS file provided by the motherboard manufacturer and write it to the burner.

Fault phenomenon: After pressing the power button, the optical drive light flashes, the motherboard power prompt light is on, and the power supply is normal, but the screen is not displayed, and there is no "drip" sound.

Fault analysis: This phenomenon occurs after the CUP is damaged, the BIOS first checks the CPU during the self-test process, the CPU is damaged and cannot pass the self-test, and the computer cannot be started.

Known workarounds: Check if the CPU is installed correctly, check if the CPU core is damaged, check if the CPU is damaged using the replacement method, and replace the CPU if it is damaged.

Fault phenomenon: there is no display or prompt when the boot is turned on, the motherboard power supply is normal, the cup is normal, the fan is normal, but the screen is not displayed. There is no "drip" sound of passing the self-test.

Fault analysis: After the computer is used for more than 3 years, the voltage of the battery that powers the BIOS settings gradually decreases, and the data cannot be saved.

Known solution: Buy the lithium battery of CR2032, replace the existing battery on the motherboard to complete the self-test normally, and then reset the BIOS parameters.

It should be stuck, it is recommended to restart it.

What is the concept of not moving? It's that the hard disk doesn't spin.

The display is not displayed.

The mouse and keyboard do not reflect.

Or is the fan inside the case stalled, and the hard drive is not spinning.

There may be bad sectors.

Go directly to the repair station to check it.

The display is not displayed.

View the connection. If there is no problem with the connection.

Check the power supply (is the monitor light on?) If you still don't see the graphics card (discrete graphics card) unplugged after checking them all.

In the form of alcohol or. Wipe the liquor clean (gold finger part).

I'm trying.

The mouse and keyboard are unresponsive.

First, check to see if the hard drive light is on.

If you want to change the cable of the hard disk, you will need to use it again.

And change the power supply (that is, the power connector connected to the hard disk) if it still can't be solved.

Try flashing the BIOS

See if you can find the drive during the self-test.

The case fan stalls.

Don't look at it, go buy one.

The computer mouse and keyboard didn't respond to what's going on.

A variety of possibilities, you need to look at your computer configuration to know more clearly. For the time being, it can only be done by the method of elimination.

1.Troubleshoot network speed issues, because games** are generally local, and poor network speed will cause the screen to freeze. **Generally no effect.

2.Computer hardware configuration or failure problems, pure configuration problems, such as CPU memory module graphics card performance is insufficient, will cause the game to get stuck, it depends on the configuration of your computer. There is also a bad sector of the hard disk will also cause it to get stuck, which can only be checked by the hard disk program.

3.System problems, what happens after the game is stuck, if there is a blue screen or no game and there is a lag or blue screen, black screen? You can consider the system problem, and the reinstallation system is.

The computer configuration is too low.
