Many people have a personal computer today, but not everyone knows how to handle it correctly. Inside the system unit there are many boards and devices related to each other using loops and cables. From the motherboard there are trails to the CD-ROM drive, to the hard disk, depending on the configuration of the PC inside the system unit, there can be a video card, a TV tuner, a network card, several “strips” of RAM, etc. D.
All devices receive energy from the power supply – it is in every computer, and converts the voltage of 220V to voltage from the network with indicators acceptable for devices of the system unit. It is with the check of the power supply that the diagnosis should be started if the computer does not turn on or works incorrectly. Low -quality power supplies fail quickly, especially if the PC is actively operated. And it’s good, if only the block itself breaks, often its breakdown entails and malfunctions of other elements. It is possible to protect the power supply itself, as well as all the devices inside the system unit using the UPS or a good network filter. Often the cause of the breakdown is a jump in voltage in the network or frequent shutdown of electricity, which is why you need to purchase additional equipment.
Voltage surges can also lead to a breakdown of the motherboard, field transistors often burn out, over time, capacitors can be swollen on the motherboard. The BIOS chip is responsible for the initial loading of the PC, which analyzes the devices. With its malfunction, the computer most likely will not start. Incorrect firmware of the motherboard, according to statistics, is one of the most common faults.
In addition to the motherboard and power supply, of course, there are many devices in the system unit. But they all break significantly less often, and the PC is almost always turned on if it is faulty, for example, a video card or CD-ROM.
If you cannot independently diagnose and eliminate the malfunction, contact the specialists. Surely near your area there is computer aid or service center. If you contact consultants, you will be asked standard questions regarding the establishment of a possible cause of breakdown. For example, if you moved the included computer, a hard drive may break – sharp shocks and shaking for this device in a working state are extremely undesirable.
In addition, computers repair is also eliminating software problems. You need to take care of the computer if you do not use any programs, delete them, do not “cllate” the computer. When going to the Internet, be sure to use antivirus programs, viruses and Trojan programs can contribute to the appearance of “dietary supplements” on a hard drive. In addition, viral programs often entail the loss of important data on PC. If your computer is under warranty, do not try to fix anything yourself – immediately contact the service centers.
