Disassembling a PC case can be a tedious job but it is necessary to know about it. Say, you want to upgrade your PC and put a new hardware component in it (such as a new video card for Sims 3 or another hard drive for your downloads). You will need, at least, some basic knowledge on how to disassemble a PC.
First off is for you to find a safe environment where you can disassemble your PC. Make sure that it’s clean and spacious. Also, having a small container for the screws might help. This will prevent mixing up, scattering and losing them. Don’t forget to remove any metal material that your hands are wearing. Wearing metal watches, rings, or bracelets while disassembling might damage your hardware components.
The very first thing you do when you disassemble a PC is to turn it off and disconnect all the power sources. This is very important. Forgetting to turn the power off, especially from the wall outlet, will cause tremendous results.
Next is to pull out all the external cables.
- The monitor cable (or the other cables with screws) isn’t just ripped off. It is unscrewed. Pulling it off directly might flatten the teeth of its screws thus making it harder for you to put it back later on.
- The Fiber Optics, patch, telephone, and modem cables are removed by pressing its clip down a bit, then pulling it out.
- Other cables such as the USB, Firewall, standard keyboard and mouse cable are just pulled out carefully.
Some computers don’t need to be unscrewed while some require you to pop out 3 or 4 screws (with the PC in the MIS lab, we had to unscrew the side panel then take the cover out). Slide the cover out and take a good look of your PC’s skeletal system. Remembering how it looked like will help a lot in case you mess up later.
Upon opening the PC’s case, you’ll see different things such as the video card, the sound card, the hard drives, the CD-ROM, and a lot of cables and wires. Carefully detach the data and power cables. This will make the job easier by allowing more room for work. If they don’t come off easily, don’t force it. Stop and figure out another way to detach it. Extra care should be observed when unplugging the power supply as it still has a power
charge in it. After, detach the drives and cards. It is better to follow a certain order (such as from top to bottom, left to right) to avoid scratching other valuable parts. It usually depends to the placement of your PC’s parts . In our case, we did it from top to bottom.
We followed this order:
- Expansion Cards
- Disk Drives
