Before starting computer disassembly, ensure the system is turned off and disconnected from the power supply. Remove any hand accessories. Place an electrostatic mat on the workbench and wear a grounding strap, connecting it to an unpainted part of the computer case to prevent static electricity buildup.
Open the computer case by removing the side panels. Note that case opening methods vary by manufacturer, so consult the manual if needed. Disconnect all internal cables from the power supply, motherboard, and devices, starting with the 24-pin ATX power connector, followed by the 4-pin 12-volt connectors, and then all SATA power connectors.
To remove the power supply, unscrew the bolts holding it to the case and slide it out. For the optical drive, locate its bay, unscrew the retaining bolts, and slide the drive out. Similarly, unscrew the bolts holding the hard disk in its bay, unmount it, and slide it out.
To remove the motherboard, unscrew the bolts in the standoffs that secure it to the side of the system case. Once these are removed, the motherboard should become loose and can be carefully taken out.
Locate the memory slots on the motherboard where the RAM sticks are installed. Unlock the tabs on both sides of the slot by pulling them down. Lightly place a finger on top of the stick for support as it is released, allowing easy removal.
First, pull the rod that locks the CPU fan and heatsink to the mounting tabs, then remove the fan. Next, lift the metal rod beside the CPU socket that holds the CPU. Note the arrow indicating the corner of the processor to its socket. Carefully remove the CPU and immediately return it after noting its specifications.
After disassembling all components, record the details of each component in an inventory form, which is crucial for tracking and reassembly.
