1. Using the instruction booklet that came with your motherboard, configure the motherboard's jumpers to reflect the CPU you purchased.

2. Open up your case, screw in the motherboard so that it is aligned with all the connectors that are facing the outside of the case, and plug the motherboard's power supply cable into the motherboard.

3. Mount the fan onto the CPU.  Insert the CPU on to the motherboard.  If you have a Slot 1 or Slot A motherboard, just plug the CPU.  If it is Socket 7 or Socket 370, bring up the lever on the socket, match the pins, and close down the lever to secure the processor into the socket.  Plug a power cable from the power supply into the fan, or plug the connector into the motherboard (depends on the fan's connector.)

4.  Locate all the add-on cards (AGP, AMR, PCI, & ISA cards) and securely plug them into the motherboard.  Then screw the brackets of the cards into the computer's case.

5. Mount the floppy drive, CD-ROM drive, hard drive, and any other removable storage drives into the case.  You may need to remove a plate from the front of your case to do this.  

6. Set up your IDE devices.  Excluding the floppy drive, if you have only two devices (e.g. Hard Drive & CD-ROM), set both jumpers to master.  If you have more than two devices, set the hard drive on master, a second device to master, and the third or forth devices on slave. 

7. Connect the floppy drive cable to the floppy drive.  Connect the two IDE cables to the IDE devices.  The hard drive must be plugged in to the primary cable (the one plugged into the Primary IDE socket on the motherboard).  Once master and one slave can be plugged in to each cable.  

8. Plug one power cable from the power supply to each of the drives.  Plug in the audio cable from the CD-ROM drive to the sound card.

9. Close the computer

10. Plug in all the external devices, such as the monitor, keyboard, mouse, speakers, and power cable to the computer.
