HOW TO DISASSEMBLE A SYSTEM UNIT 💻 

Step 1; Outer Casing 


🌸 First off, unscrew the four screws on the back of the computer. On most computer cases, there will be large knobs that you can unscrew by hand or by screw driver on the back-right side of the computer. Once the screws removed then just slide it off .

Step 2 ; System fan 


🌸 most computers have 2 fans 
 a) system fan -the one blowing air to the computer
b) CPU fan - the one blowing air onto the CPU heat sink .

🌸 unplug the fan from motherboard . Next , you need to unscrew the fan from the outside . You should now be able to lift the fan out the PC .

Step 3 ; CPU fan 






🌸 The CPU fan is located right on top of the CPU heat sink . It is hard to access because the CPU fan plugs into the motherboard . 
🌸 The 4 screws securing it in place is removed in order to remove the fan from the heat sink .

  • Motherboard (very large connector/plug)
  • CD/DVD drive[s] power
  • Internal hard drive power
  • Portable hard drive slot power
 🌸 once everything is unplugged , unscrew the 4 holding the power supply in place . Next , push the power supply from outside and then lift it out . 


Step 5 ; CD-ROM Drive 








🌸 First, unplug the ribbon from the back of the drive. 

🌸Once that is completed, pull on the tab securing the drive in place, then push it out from the inside


Step 6; Hard Disk 


 🌸 we need to de-attach the connector at the back of the slot and unplug the others from the motherboard 

🌸 Unscrew 4 screw securing it in place in order to remove the hard disk . 


Step 7; RAM 



 🌸To remove the RAM, push down on both tabs holding the RAM in place, which are located at both ends of the RAM
