Repair Computers

Disassemble & Reassemble
Repair computers and upgrading are the two main reasons people need to open a computer.


For this purpose the first step when repairing a computer is knowing how to take one a part and put it back together.
For this task all you need is a toolkit and a antistatic wrist strap.
Taking the computer a part is the easiest step, putting it back together and making it work the same as it was before required a little bit of disciplin and documentation.

Disassembling steps
Step1: Documentation and preparation
Step2: Disconnecting external peripherals
Step3: Removing the cover and Identifying the parts
Step4: removing the video card and other cards
Step5: removing the drives
Step6: removing power supply computers
Step7: removing computers memories
Step8: removing the mother board
Step9: removing the cpu fan
Step10: removing the cpu
Once you have successfully done all the steps and taking a part your computer it’s time to put the parts back together and make your PC worked as it was.
Let me share with you my experience. As a handy man, one day I open my computer and start putting the parts a side without knowing anything about what I was doing. I successfully disassemble the computer but I could not get it back to work as it was.
I had to get help from a technician friend who help me reassemble correctly. One of the thing he taught me and I have learned is documentation is very important in the technical field
documentation to collect
• Motherboard documentation
• List of the installed expansion cards
• The operating system that was running in your PC
• Current configuration of the computer( model of the drives…..)
List of the tools needed to repair computers
• Screwdrivers: one large and one small flathead and a set of Philips head (sometimes called a cross)
• Tweezers: convenient for picking up lost parts
• Needle-nose pliers: think of them as an extension of your finger
• Compressed air: to remove dust
• flashlight: for seeing in dark places
• curved hemostats: for picking up and holding small parts
• the antistatic wrist strap: use to prevent electro static discharge (ESD)
Once you have disassembled and reassemble your computer 2 or 3 times successfully, you are on your way to be a good computer technician and will be able to upgrade and repair computers
Remember never force a part, never screw to tight.
