In this article I will explain about all the parts inside a PC. I will also talk about replacing or repairing them one by one in order to bring the computer back to life. |
A PC consists of many parts that can be repaired or replaced. This includes a casing that is the outside of the PC. A PC usually has three essential cables which include a power cable, a keyboard cable and finally a mouse cord. If we look inside the PC we see many parts. The first one is called power supply where we connect the power cord. This unit power distribution function inside a computer system. The power supply connects to a blue or green color board normally known as motherboard which is also called as logicboard, a term introduced by Apple in their Mac desktops and MacBooks. As the name suggest, this board works like a mother that help connect all PC parts together. The next part inside the box is the RAM (Random Access Memory). This part helps computer run its programs as long as the computer us turned on. The number of RAM sticks can range from 1 to 6. The next part is the CPU. The CPU normally has a fan and a heatsink (which take away heat from the CPU with the help of fan) on top of it. CPU is usually confused with the PC box or tower. CPU is the part that processes all operations for example all programming is executed inside the CPU. The next one is the graphics card. The graphics card has two types. Some PCs come with a built-in video chip (graphics adapter). This part actually displays all the programming or processing results on the computer screen. There are some extra ports in PCs that can be used to install a dedicated graphics card that does the same function like a graphics adapter i.e. displaying output on the screen (I will explain later what a monitor is).
Other parts that can be installed in these ports could be a modem, a USB splitter, a sound card (most of modern computers are coming with built-in sound card), SCSI card or a wireless PCI card (used to connect the PC to a router without wire for Internet connectivity). The other part that is most important is called a hard drive. The hard drive stores all data, programs, files like photos, documents, videos and other data. Old computers also come with a device called CD or DVD drive. This is used to copy data from and to a CD or DVD disc. This device can also be used to install programs on the computer. A Floppy diskette drive was part of very old computers. This was widely used when there was no CD or DVD drive. It is not coming with new computers anymore. There are some peripherals that are partially parts of a PC system. These include USB flash drives, Printers, Scanners and some other parts. The USB flash drives can be connected to the USB port of a PC. These flash devices are used to store data for mobility purpose. The printers are used to print, scan and send faxes. The last but not the least is the monitor that shows all the results and outputs. This device connects to the video adapter or graphics card on a computer.
Now let me talk about repairs. A Power supply can be one of the several reasons of no power in the PC. When there is no power, the PC can be brought back to life by replacing its power supply. If a motherboard is dead, there will be no life in the system. This could be repaired or replaced. About RAM, because there are more than one RAM slots, usually one or two chips might have problem so those can be replaced or if there is a problem with the RAM slot then a quick solution would be to install bigger RAM in one of the good slots. The CPU can be replaced in most PCs. The same can be done with heatsink or fan. Hard drive can be changed or repair and fixed which can lead to data recovery. CD or DVD, Floppy drive, graphics card, or sound cards can be replaced.
