The system unit is a whole complex of devices that interact closely with each other. This is a fairly reliable system, provided that it was originally assembled from high-quality components and specialists who know their job. But sometimes problems arise that require intervention, but the average PC user vaguely imagines the system unit device . Some problems require the intervention of qualified craftsmen, and some can be resolved at home. Repairing system units will not be a problem after reading this article. So, let's begin.
What is a system unit? This is a set of devices that provide computer operation. Their list includes the motherboard and
central processor, RAM, video card, hard drive (hard drive), network and
sound cards, power supply and a number of other optional devices.
Computer instability is most often associated with software problems. That is, it is possible to deal with this only at the level of the operating system, without physical interference in the hardware of the computer. However, there are problems in which the user still needs to repair the system unit.
For example, a common problem is overheating of components. The
CPU most often suffers from this
. If at the initial stage you do not think over an effective
cooling system, then in the future this may cause unstable computer operation. Constant overloads, shutdowns are direct evidence that the processor overheats.
Repair of the system unit may also be necessary if the computer simply does not turn on. Most likely, the reason lies in the failed power supply. Unfortunately, they are rarely amenable to repair, it is easier to change.
Various artifacts on the screen, especially during a computer game, are direct evidence that the video card is not functioning properly. Sometimes reinstalling drivers or updating them to the latest version helps. If not, you should check the cooling system in the same way as on the central processor.
By the way, in order to check the temperature of certain components, it is enough to install third-party software, for example, Everest. This complex will also help diagnose components. In order to find out the peak temperature of a device in the system unit, contact the manufacturer. For example, for processors this value should not exceed 70 degrees Celsius.
But the repair of the system unit does not always succeed on its own. For example, swollen capacitors on the motherboard. This phenomenon is associated with periodic power surges in the network or with the factory defect of the board itself. In the service center, the capacitors can be re-soldered, replaced with new ones, or they will offer to replace the entire motherboard.
In any case, if you are sure that it will not be possible to repair the system unit yourself, we recommend contacting specialists. This will save you nerves and time, and also save you from larger breakdowns.
