Read why the computer is noisy and what to do. All the reasons for the strong noise of the power supply, the system unit. Ways to fix yourself.

Almost every user of a stationary computer has encountered a situation where extraneous noise is heard from the system unit. There may be several reasons for this. If the computer began to make noise, then measures must be taken immediately. This can be a sign of a serious breakdown or cause the main components of the PC to fail.

Where is the noise coming from in the computer?

First of all, find out why the computer is noisy. To do this, listen to him while you work. Most often, users complain about the noise in the evenings, since at this time it is heard more clearly. Extraneous sounds can occur for various reasons:

1. Features of the hard drive. Old full-sized models emitted an unpleasant rattle while writing files or reading them, if it is too distinct, then it's time to check the performance of your media - because you don't want it to fail at the most important moment for you. Modern solid state drives are silent, if you notice a grinding noise during their operation, you need to check the motherboard and the power slot.
2. The video card can also be a source of noise, especially if you have installed a powerful variant with a large cooler or even multiple fans on your PC. Most often, the cause is dust between the blades of the cooler or its design features.
3. The processor fan also accumulates dust in itself, in addition, pollution can also be found on its axis, which leads to braking, grinding and other extraneous sounds. The number of revolutions of the cooler also decreases with the accumulation of dust, which leads to a computer freeze and a decrease in its speed.
4. Another fan that can make loud noise is located in the power supply. Some experts recommend changing the block every 2-3 years. This procedure can give you confidence that your computer is in full working order.
5. The optical drive may make unpleasant sounds while reading the disc, which indicates a malfunction. If you notice them, then be prepared to abandon this device in favor of additional inputs for flash drives or replace it with a new one. The optical drive is beyond repair. If you hear noise at the moment when there is no disk in the device, then you should look for it elsewhere, the drive starts working only after the storage drive is placed in it.
6. The appearance of dents, chips and cracks on the boards can also become a source of noise. Coolers force air inside the device, which leads to whistling and rattling of the parts inside it.
7. If you are assembling a computer yourself, you need to carefully check the fastening of the parts. Insufficiently tightened bolts, missing cable ties, and vibration from computer operation lead to rattling.

These are the main reasons due to which extraneous noise occurs when the computer is running. Now consider what can be done at home. Not all of these problems can be solved, sometimes you just need to change one of the component devices.

Noisy computer? Clean the cooler from dust!

The cooler, located on the central processor, attracts the maximum amount of dust. As a result, it begins to hum, crackle, rotates several times slower. In advanced cases, the computer completely stops starting. This is due to the fact that thermal paste dries out due to periodic overheating. It must be replaced during the cleaning process.

If your computer is under warranty, do not open the system unit yourself, but take it to an official service center.

Dust cleaning refers to paid procedures, but the masters will restore all seals and if the hard drive, motherboard or other equipment breaks down, you can claim a warranty replacement or repair.

For out-of-warranty computers, do the following:

1. Shut down the computer completely.
2. Remove the side cover from the system unit.
3. Disconnect the fan from the motherboard, the connector is usually located next to the heatsink.
4. Remove the radiator and cooler together. To do this, press a small lever located under it or on the side.
5. Use a small vacuum cleaner, hair dryer, or cotton buds to remove all dust from the cooler.
6. Thermal paste is smeared on the bottom of the radiator, if it looks like dried chewing gum, then you need to remove its remnants with a cotton pad and then apply a new one.
7. Reassemble in reverse order.

You can buy thermal paste at any PC hardware store and it comes in small tubes. Do not use wet wipes to clean the radiator and cooler. Do this work only with dry improvised means - brushes, cotton swabs. Otherwise, a closure cannot be avoided. It is very good to blow dust with air. It is best to use a not too powerful vacuum cleaner, for example, designed to clean the interior of a car.

If necessary, if the fan in the computer makes noise after cleaning, you can disassemble the cooler and lubricate its axis with silicone. To do this, you need to peel off the sticker from the cooler, remove the small cap and drop a little lubricant into the opened hole. This should only be done if your computer is old. New PCs do not need to be completely disassembled.

How to clean the power supply

Similarly, you need to do if the computer's power supply is noisy due to accumulated dust. You need to open the assembly, clean it and lubricate the cooler axle. In this case, you need to use the same improvised means. Only you should remember that the old Soviet vacuum cleaners are not suitable for cleaning power supplies - they are capable of producing electrostatic charges that will destroy the board of this node.

Some power supplies are not disassembled in this case, you need to replace the entire assembly. If you find that the computer is noisy when turned on due to the power supply, then you need to carefully inspect it during operation. Sometimes gratings are installed on the back, which are fastened with screws. Over time, the mounts loosen and the fan blades can touch the grille. In this case, there are two ways out - remove it entirely or tighten the screws.

Hard disk check

There is another reason why the computer makes a lot of noise. Grinding, tapping when accessing the hard drive is possible only if you use its old bulky model. Now such media are not installed on computers. Every year hard drives become more and more compact. Replace your old HDD with a solid state one.

You also need to check how well the media is fixed inside the system unit. If necessary, screw in the screws and place a thin rubber pad under the disk. Smaller media can fit into the slots if you buy a special case for them.

Checking the operation of the video card

Look at the video card. It can also be a source of noise, but a simple cleaning will not be able to get rid of the problem. The video card is upside down, and it also has a small cooler. Due to the peculiarities of its placement, after the ingress of dust, the axis of the component shifts.

In this case, disassemble and clean the cooler, lubricate the axis with silicone. Try twisting the cooler slightly to see where the axis has shifted. If the blades touch one of the walls of the body, then you need to cut it off slightly. Some masters even recommend removing the maximum amount of the protective cover for the cooler, while other experts believe that in case of such a breakdown, you need to change the video card or look for a new fan that is suitable in size.

What else can you do if your computer is noisy?

If you find cracks and chips on the boards, a breakdown of the optical disk, then you should not fix the problem yourself - in most cases, only the replacement of damaged nodes can save you from extraneous noise.

Did all of the above help? And your computer is making a lot of noise. What to do? In this case, you will only have to upgrade your computer.

To do this, you need to do:

1. Replace the air cooling system with a liquid one. This option is suitable for gamers who value high performance and uptime of the computer. It also makes sense to use liquid cooling if you work on a PC, performing actions using programs that require high performance. You should not put a liquid system on a standard office computer or one that is used to listen to music, surf the Internet. In this case, the cost of the system will not justify itself.
2. If you decide to leave the system air, then you should pick up modern silent coolers in the store with PC components. Before buying, pay attention to the information about the fan located on the sticker. It indicates the required current for the operation of the cooler, the number of revolutions. Measure the diameter of the device to purchase an analogue that fits the size.
3. If there is no reason for the noise, you need to consider placing your PC nodes in a new case. Very often, people who assemble powerful systems on the basis of a simple office box are faced with the fact that the finished machine is very noisy. It only means that the case is not suitable for soundproofing characteristics. Replace it with a new one capable of absorbing vibration from running equipment.

Remember that you can work calmly only if you regularly monitor the cleanliness inside the system unit. If you are not confident in your abilities and are afraid of not being able to cope with cleaning coolers, you should bring your PC to a service center for preventive cleaning. This service is paid, but it is much cheaper than a new processor or video card.

Now you are not afraid of the situation when the computer makes noise. What to do in it - you know. If you have any questions, you can ask them in the comments. Share information with friends, discuss.
