In order for the computer to work without failures and the performance was at a high level, you need to be careful when assembling the "stuffing" of the system unit. If you decide to take on this business, it is better to check several times what and where you are connecting, because there are no cheap parts inside the system unit.
Connecting the hard drive
Now hard drives have SATA connectors. To connect a hard drive, you need: a special cable for transferring information and an adapter for recording a disc. Difficulties can arise if the adapter is not connected correctly. Although there is a special key on the connector that prevents incorrect connection, some still manage to connect it incorrectly, although it takes a lot of effort to do this. Doing so will burn all electronics in the hard disk board.
Video card
While assembling a computer, inadvertently, you can forget to connect additional power to the video card, and this will be, perhaps, the most harmless mistake. Eliminating this is not difficult and without sad consequences. An incorrect connection can be noticed when starting the game, it will become very slow. This is easily eliminated. Having opened the case of the system unit, we look for the necessary cable and connect it to the video card.
Thermal paste
If you need to replace the thermal paste, you must carefully remove the cooler from the processor and wipe off the old paste. The new one should be applied over the entire area of the processor in a thin and even layer without tears and not leave any bare spots. Excess paste that has ended up outside the processor must be carefully removed. Incorrect application of thermal paste can lead to overheating of the central processor, and this already affects the performance of the entire computer. This will be noticeable by braking when performing complex operations. The thermal paste must be changed every six months.
Motherboard
The mistake is common for beginners, but it happens also for experienced ones. When you buy a computer case, a sleeve is included with it. It serves to securely attach the motherboard to the wall of the system unit. The sleeves are attached to the case, then the motherboard is leaned against them and only then they are screwed on. But it happens that due to lack of experience, the motherboard is attached directly to the case without the use of sleeves. The result of such an installation will be sad, the entire motherboard will burn out, and accordingly you will need to buy a new one.
USB connectors
In the front of the system unit there are special USB connectors for various devices (flash drive, printer, phone, camera). Their location in the front makes them very easy to use. But before using these connectors, you must first install them on the motherboard.
If the installation was not carried out correctly, then the first connected device will instantly become unusable. It will be good if it is an ordinary flash drive, but if it is an expensive laser printer, it will be very disappointing to fly into a pretty penny due to inattention. It is better to check everything again to prevent such consequences.
