Wear an anti-static strip.
Place the new motherboard on an anti-static mat.
Don’t use force to connect and disconnect any cables.

Install the new motherboard

Take the new motherboard out of the anti-static bag and set it on the anti-static mat.
Set jumpers on the motherboard to match the installed CPU according to the motherboard manufacturer’s manual.
Find the holes in the motherboard for the metal spacers and plastic standoffs and then screw any metal spacers into the computer case in the proper positions to align with the screw holes on the motherboard.
Install the plastic standoffs into the motherboard from underneath until they are firmly snapped into place.
Mount the motherboard into the computer case by placing it to ensure that all standoffs engage the case.
Secure the screws and any plastic washers to fix the motherboard on the case.
Connect the power cable into both connectors P8 and P9.
Connect the power cable to the cooling fan of the CPU.

It is assumed that the motherboard has onboard I/O card, video adapter card and sound card. The following steps show the connection of the signal cables of the floppy disk drive, the hard disk drive and indicators in the front panel.

Connect the 34-pin floppy cable between the connector (marked FDD) on the motherboard and the back of the floppy disk drive.
Connect the 40-pin IDE cable between the primary IDE connector on the motherboard and the rear of the hard disk drive.
Connect the 40-pin IDE cable between the secondary IDE connector on the motherboard and the back of the CD-ROM drive.
Connect the audio cable between the sound card and the back of the CD-ROM drive.
Connect the power cables to all internal components such as the floppy disk, the hard drive and the CD-ROM drive.
Connect the power indicator LED cable from the front panel to the power LED connector on the motherboard.
Connect RESET switch cable from the front panel to the RESET connector on the motherboard.
Connect hard disk drive access indicator cable to the connector on the motherboard.
Place the case over the system unit.
Secure all screws on the side and back of the system unit.
Connect the power cord to the system unit.
Plug the power cord into the wall outlet.
Turn on the computer and test to make sure that it is working.
