    It seems that it is a virus that has been automatically muted by the waveform, and I want to find you a waveform mute virus killing tool on the Internet, but I can't find it. It seems that it can only be cleared manually:

    Boot mutes virus.

    Power on mute. English Name:

    Process: Unknown.

    Phenomenon: The computer is automatically muted when it is turned on, that is, the computer is automatically muted after it is turned on, even if you turn it over, it will be muted again after a few minutes. In the system disk, the C disk, and the windows file is generated.

    Not iExplorer! There is also the same file in temp. This is available in the Launch.

    2. Remove the auto-mute virus at startup.

    According to the phenomenon of auto-mute at boot and the files it generates, we can enter safe mode to delete boot mute virus.

    The first step is to enter the safe mode (press the F8 key when the computer is turned on). Open my computer and delete the C drive and temp.

    lgsyzr, o2flash, and the processing results are the same as above!

    Step 3: Enter the registry (enter regedit in the run): press F3 to find the following items: LGSYZR, O2flash, ALGA, iexp1ore. Delete all the searched value items.

    Step 4: Start-Run. Enter msconfig. Banned alga and iexp1ore in the startup items! Restart your computer. Then go to the system and delete the alga file (search is OK, so hurry up).

    And then it's good to start with the beginning again.

    For sound card issues, it's best to install an audio control that can solve this problem.

    For example: Audio Manager.

    Not enough detailed. Is it the noise or the sound output that suddenly isn't there? If it is noise, it should be the intelligent power-saving function of the computer, the notebook is not used for a period of time, the temperature drops to a certain level, and the cooling fan will automatically stop, thus reducing the noise (if the hard disk is also set to be idle for a period of time to turn off, there will be no sound), in fact, this is not a problem, rest assured to use it; If there is no sound from the sound output, it may be that the sound card driver is faulty, please check the hardware device manager, and if necessary, consider reinstalling the sound card driver and rebooting.

    Good luck!

If so, you can try: open the Control Panel - select [Hardware and Sound] - under the [Sound] item there is [Manage Audio Devices], open the option, click [Communication], check if your computer will "When Windows detects communication activity" and "Mute all other sounds", if so, select "Do nothing", OK.

    Try turning up the volume.

    It is recommended to force restart the system first.

    Go to the after-sales center and ask the engineer to detect whether it is a problem with the screen or the motherboard.

    Try to connect to your PC and use the [Restart] function in PP Assistant, iTools, etc.

    Update the system. Notebook computer (abbreviation: notebook, nb), also known as notebook, laptop or laptop computer in Chinese

Chase - water.

Water is the most direct killer of laptops, but there are also many people who tend to overlook many potential "water". As you know, the motherboard of a notebook is much more integrated than that of a desktop due to its small size, which leads to a relatively high production cost. If an accident occurs on the motherboard, the cost of replacing the motherboard generally accounts for about one-third of the whole machine, because this kind of accident is generally a man-made fault and is not included in the warranty, so the repair cost can be said to be jaw-dropping. >>>More
