There are lots of people out there who are knowledgeable in handling computer hardware most especially the inner workings of the tower. Aside from knowing the parts and what they do, it is also just as important to know how to install them correctly and most importantly, safely. There are lots of ways to put those parts in and out from your computer tower.
First and foremost, it is important to plan ahead. What do you need to do? Are you installing something or removing something? Usually, you will handle PCB (printed circuit board) hardware such as the motherboard and graphics card. The first thing you should do is to touch something metal (or something that conducts electricity such as the case of the PC itself). Touching these circuit boards while you have static electricity may damage those boards and may give you a little shock at that.
Now, every time you open up your PC tower and do some stuff inside, always have ample lighting. You may hit something inside that could make your PC inoperable or you may even get hurt so make sure you have enough light to see everything inside. Ask someone to assist you if you can. Have them hold the flashlight for you or something.
Before tinkering with the innards of your PC, make sure the power is off and the power cord is unplugged. This may cause a short in your hardware especially if you touch the parts with metals such as the screwdriver itself. This is to avoid being electrocuted as well. Remember, power supplies are usually very powerful.
This is very common especially those who are doing it for the first time. The next safety precaution is to use the right tools for the job. If you have a screw with a cross head, use a Phillips screwdriver. Don’t force the flat tip screwdriver. There are possible dangers such as if you slip, your hand may hit the interior of the tower and it may result to injuries. Plus, you’ll be exerting unnecessary extra effort.
Watch out for corners. Pulling the cords, cables, and plugs within the tower could be dangerous. Let’s say you are having a hard time unplugging an IDE cable from the top DVD drive. After pulling it so hard, you hit the corner of the power supply (yep, happened to me once). This could lead to injuries and could happen almost anywhere inside the tower so watch out and be mindful. As much as possible, don’t tangle the lines especially the power cords and the data cables. Keep them away from the fans.
It is also advisable to wear thin gloves for hygiene. Oh, you can try wearing thicker gloves but you probably would have a hard time with small screws and other small stuff. So wear the thin but heavy duty ones as the doctors and nurses wear.
Accidents could happen anywhere so it won’t really hurt to always be safe even when you’re just working in your computer. Don’t get too excited especially if you’re installing a more powerful device. Always stay safe and do it right.
