9.2. Assembling a Disassembled PC 

Reassembling a PC is just the reverse order of disassembling. The steps are: 

 Place the power supply unit and its on/off switch at proper location. 

 Insert processor in the ZIF socket of the motherboard with proper direction 

 Insert the RAM card in its slots of the motherboard. 

 Place the Motherboard on the steel plate of the chassis and connect the plate with the chassis. 

 Connect the connectors of turbo switch, speaker, disk lights etc. and the power supply cable P8 and P9 with the motherboard. Be careful about the proper position of the two power connectors. 

 Insert the disk drives at their locations and connect them to the I/O card (or motherboard in newer PCs) and power supply unit with cables. 

 Insert the expansion cards in the slots of the motherboard. 

 Close the casing. 

9.3. Connecting Cables 

Connecting the cables is an important step of assembling, because it possible to place the connectors in opposite directions and then the PC will not work. 

9.3.1. Finding the Wire-1 on a Cable 

The cable connection becomes easier if the wire-1 can be found. Most of the flat cables (cable that has many parallel wires) has a dark line wire. This is the wire-1. The cable should be connected with the I/O card (or motherboard in modern computers) or disk drives in such a way that cable’s wire-1 connects with motherboard or disk drive’s connector’s pin-1.
