Your computer may be experiencing sound problems like buzzing, breaking of the sound stream or your computer may not have sound at all, and other problems. If you are not experienced with a particular problem it is best to call some computer repair service.

If you are wondering what causes your sound card to stop working or makes problems, you should know that there are many things you can check by yourself.

See if the speakers are plugged into a power source. There are some old speakers that used batteries as a power source, if you have those check the batteries because they may be empty.

There is a big number of old sound adapters and laptops that have manual volume dial. You should try to position your volume dial in the middle and not to far on the sides, because it can turn off the volume.

Have you installed the driver for your sound card?

There are cases when people reinstall operating systems on their personal computers and they forget to install the drivers. Some motherboards have soundcards implemented on them and you can find sound drivers on installation disc for your motherboard. Sound cards that are not implemented on motherboards have driver installation discs too. Best way is to find most recent driver for particular sound device and download it from device manufacturer’s official site. Then you can install it and solve the problem.

There are cases when system plays audio files fine but it can’t play music CD’s. Look for a hidden mute in software, maybe someone muted it or you did it by accident, there are cases when it is auto/muted. Also check cables in your computer tower, maybe some of the cables are not connected as they should be.

If you only have built in integrated motherboard sound support you should check if it is enabled in CMOS. And if you are using a sound card you should check if the motherboard sound device is disabled, it can make a conflict and mute all sounds. There is a possibility when the system can’t recognize your sound card after previous steps. Try to unplug your sound card manually if it’s a plug and play sound card, and remove any other adapters except your video card. After those reboot your computer and let your BIOS adjust and configure. After that step shut down your computer and replace your sound card, just to see if that can get it going. If it works now, you might have problems again when you put the other adapters back in. If you do it one at a time you can know where the conflict appears.

If none of the above helps, it is advised to call some help and support center or a computer repair service. They can determine if the sound card can be fixed or you maybe need to buy another. These services are great and they can accurately find what the problem is and fix computer in no time.

There are many symptoms for video card problems like crashes, display corruption hangs, and more. There are many types and models of video cards, and there are many solutions for the problems that can appear.

You should first check if the drivers are installed properly. You can look for them on the hardware installation disc which you usually get with your graphic card, or you could look for them on the internet. Just install the drivers if you don’t have them or you can update the existing drivers with new ones.

You should also install the newest motherboard chipset drivers because this could cause a problem too, because people usually only check the graphic card drivers.

There is one problem with games that crash. It is often believed that it is related to graphic cards, but it is not always the case. Sound drivers can be a problem in this particular case too, because it happens that the sound drivers are damaged and could cause a crash off a game. You should first disable your sound card and see if the game crashes and if it does not crash it’s the sound drivers. If it crashes again after disabling the sound, you should check for the newest drivers for that hardware.

There is one problem that can occur because of the cooling as well. The graphic card has its own cooler and it can happen that the cooler drops dead. That can happen if the cooler is dusty, so dust blocks him, or if there are smokers near the computer so tar gathers on the cooler. You can try to clean the cooler and see if it works. If you can’t get your cooler to work, you should consider sending your video card to a repair service or to purchase a new one.

Sometimes your graphic card may be overheating if you overclocked it. In that case just try to underclock it and it should work fine and it should not make any problem. Or you can try and buy a better cooling system for your personal computer tower.

Sometimes a physical problem for your graphic card can occur. It may be damaged if the computer tower was roughly handled, or it may be disconnected from the motherboard itself. Just reconnect it to the motherboard if this is the problem. If it’s to damaged for you to deal with, you can ask an IT service to repair it for you or you can buy a new one.

You can also check your CPU power and memory capacity. Some games can offer a big deal of problems when it comes to your graphics, when cpu or memory is not at least on the lowest level for that particular game. It is best to play games with a recommended hardware, knowing that you meet these requirements.

You can also check your power supply unit, because it happens that power supply units can’t bring enough power to all of the computer’s hardware components. In that case it is best to go and buy another stronger one, because it could easily solve the problem.

There are many problems with video cards but most of them have a software nature, most of the times a plain installation or reinstallation of the drivers, or adjusting the settings can solve the problem.
