a , Why does my computer suddenly play a piece of music or a strange sound
1. 1. First, make sure there is no problem with the hardware. If there is no problem with the speaker and the sound card, and if you have tested it on other machines and it is indeed in good condition, then you can continue reading.
2. 2. Make sure all the connecting lines are completely correct. Then power on the speaker and turn on the volume switch.
3. 3. Correctly install the driver for the sound card. If it is an onboard sound card, it is best to install the driver provided on the motherboard driver disk. (In fact, when the computer makes no sound, it is often because the sound card driver is incorrect. Generally, after the sound card driver is installed, there will be a small speaker icon in the taskbar in the lower right corner.)
4. 4. If you are sure that the driver is installed correctly, then take a look at the volume settings in the computer. The specific method is: double-click the small speaker icon in the taskbar, and in the pop-up \”Volume Control\” dialog box, check whether the volume in \”Volume Control\” and \”Waveform\” are turned to the minimum or set to mute. . If these two options are not available in the dialog box, please click the \”Options\” menu – select \”Properties\” – click \”Select \”Volume Control\” and \”Waveform\” in \”Display the following volume control\”, and then make the correct settings. Note: The fourth step can only be set after the sound card driver is correctly installed. dSpecial reminder: In fact, there are many Sometimes, the reason why the computer does not work properly is a minor problem or soft fault. If you analyze it carefully, the problem can often be easily solved.
2. Why does Lenovo computer have no sound after reinstalling the system
1. First, let’s inspect the hardware equipment, such as sound cards, speakers and other equipment. Check whether the connections of these devices are normal. If it is an independent sound card, remove the sound card, wipe off the dirt on the sound card with an eraser, and then plug it back in to check whether the sound is normal.
2. In terms of software, the sound card driver may have failed due to computer reinstallation. Right-click [My Computer-Properties-Hardware-Device Manager] and open all devices. Find the [Sound, Video, and Game Controllers] option, expand it, find the sound card, right-click it, and then select [Properties-General-Device Usage-Select]. Now just keep OK. You can also find the Hardware Update Wizard above. Automatically install software.
3. If the above method does not work, try downloading a driver wizard on your computer, and then use the driver wizard software to detect the computer sound card driver. If there is any abnormality, re-download and install the driver. After the repair is completed, check whether the computer sound is normal.
4. Turn on the computer and hold down the del key. Go to the BIOS setting interface and check whether the audio device is blocked. If you don\’t know how to read the BIOS, find someone who knows computers or take it to a repair shop.
5. The last method is to replace the computer with a new sound card. Usually the sound card fails and causes no sound.
3. When watching a video on a web page, there is sound but no picture. How to solve the problem?
1. When watching a video on a web page, there is sound. No picture is caused by game crashes. The reasons and solutions are as follows. 4. Game crashes caused by excessive graphics card and GPU usage: While playing games, open hardware monitoring software (such as Game Plus, etc.) to check whether the graphics card is used excessively. High.
2. SolutionMethod: The graphics card configuration is insufficient, which can be solved by upgrading to a better graphics card. Or reduce the frequency of the graphics card through the tools officially provided by the graphics card (such as MSI, etc.).
4. Why does my computer *** sometimes have sound and sometimes no sound *** how should I check
1. When there is no sound, check whether there is a volume icon in the lower right corner. If so, double-click the volume icon and look at the \”Volume Control\” and \”Waveform\” columns. Is it muted? If so, please turn it on
2. If there is no volume icon in the lower right corner, open the control panel and open the sound and audio devices , look at the device volume options, here to see if the sound is muted.
3. Open the device manager and see if there is a question mark or exclamation mark in the sound part? If possible, try reinstalling the sound card driver.
4. If the problem still cannot be solved, have you installed another PCI device that caused a resource conflict? Try changing the sound card or another PCI device. slot, might do the trick!
5. Some integrated sound cards will be unable to install the driver after being used for a period of time. There seems to be no good way to solve this problem. You can try Install an external sound card to see what the problem is!
6. It may also be a software problem. Try another software. We recommend Super Jieba 35007. It may be a virus problem. Try entering safe mode to kill the virus.
5. When the computer is running normally, will the host have sound?
1. The most common situation: the CPU fan dust is too thick and the fan bearings are aging, causing the computer host to be loud. Currently, most CPU radiators are equipped with fans to achieve rapid heat dissipation. The computer has been used for a long time. A lot of dust will accumulate on the CPU cooling fan, which will hinder the normal rotation of the fan and cause noise. You only need to clean the dust. But sometimes even if you clean the dust on the CPU fan, there will still be noise. This It is because the bearings of the CPU fan are aging or dry due to lack of oil. There is a gap between the bearings, causing the sound of collision back and forth when rotating. In this case, you can put a few drops of sewing machine oil into the fan bearing. If it still doesn\’t work, you can only replace it.The fan has been replaced. The price of a CPU fan is generally around 15 to 50 yuan.
2. The power supply fan is dusty or aged, causing the computer host to make a loud sound, and the power supply is also It is equipped with a fan to dissipate heat, so it will accumulate dust or deteriorate over time. Since the power supply fan is packaged inside the power supply, cleaning the dust from the power supply fan is a little troublesome. It is best to use a hair dryer specially used for computer maintenance to blow out the dust. , if not, the hair dryer at home can be used as a substitute, but the temperature of the wind should not be overheated, preferably cold air. Friends with hands-on skills can also disassemble the power supply fan (novices should not try this) to clean it.
3. The graphics card fan is dusty or aged, causing the computer host to make a loud sound. Most graphics cards are also equipped with cooling fans (some use heat sinks directly, Fanless) The cleaning method is the same as above. It is recommended to replace the fan with a new one.
4. The computer host is loud due to the aging of the hard disk. If possible, the solid state drive can be replaced.
6. The computer volume is turned up to the maximum, why is there no sound
1. Now check the computer device manager to see if there is an exclamation mark in the sound card section. If there is, reinstall the sound card driver. If you don\’t know how to check the installation, just download the special software to test the installation. The special software includes \”Drive Life\” or \”Drive Wizard\”. After these two softwares are downloaded and installed, they will automatically detect reminders. Just follow the prompts to select the operation.
2. There is another possibility that the computer output part, that is, your speaker jack, or the audio cable is broken. This is very common. You can try it with headphones. See if you can hear the sound.
