It is important for you to be familiar with the different components before attempting to disassemble it. Disassembling a computer is not a tough task, but for beginners it surely is. I will explain to you easy ways to disassemble your computer either for cleaning or replacing and component.

1. Cut the Power

This is an important step before starting disassembling any electrical device. Same goes for computer. Remove all the connections from the outlets before disassembling the computer. This will keep you from being electrocuted.

2. Open the CPU Case

You first have to look if your CPU casing has any screws or it just needs a slide to come off. Don't use force to remove the casing. Remove the screws if any or slide it slowly away from the CPU. Different CPU DESIGNS have different method for removing the case. Follow them carefully.

3. Make a Note

If you are new to computers, it is essential for you to take a snap or note of each and everything inside the computer. This will assist you later when reassembling. You should have a clear idea of each and everything and their connections... So make a note for all the hardware that are connected and  also POINT out the wire that plugged into the MOTHER board

4. Disconnecting Cards

Cards are usually positioned and secured with screws. It is important to remove the screws before pulling them out of their slots. Don't apply too much force to pull them to avoid any damage to them. Remove all the cards like, sound card, VGA card, and memory card (RAM) etc. memory cards are usually comes in two modules SIMM and DIMM. Both types are modules are usually secured with tabs plastic or metal. You just need to push these tabs to pull these modules out.

5. Disconnecting Drives

Now you ready to remove the drives from the system. Remove all the connections of the drives, unscrew them and take them out of the system carefully. Disk drives usually contain hard drive and floppy drive. CD drive is also there; remove that also by removing the screws.

6. Remove Motherboard (If needed)

Once you have removed all the other components from the system, now you can easily remove the motherboard from the system. Motherboard is the main board on which all the other components are connected. Motherboard is usually secured in place with screws. Remove the screws and carefully remove the board from the system..

7.  Clean the hardwares and put it back carefully

These points will surely help you to disassemble the computer with minimum of hesitation. You will do well as far as you follow the given points. Another point which you need to keep in mind is to keep all the disassemble components in a secure place and treat them gently..

Hi Rajesh,
Jiths explanation is a good step-by-step guide, but care must be taken when handling computer hardware such as motherboards, memory modules and computer cards as these are sensitive to electrostatic discharge. You should use an electrostatic matt and wristband to avoid damage to the components.
I would just open up the case and use a hand vacume cleaner to remove dust without touching the components. You could also use a can of compressed air to blow the dust away.
