Install Replace and Maintain a Motherboard

If motherboard fails or an upgrade to a faster CPU or memory needs newer motherboard then old motherboard is replaced. New motherboard should be compatible with form factor, SMPS and other devices. Driver software may be needed for proper working of devices.

Removing Motherboard

First, power off and disconnect every cable from the outside of PC. Use anti-static device to open chassis cover and disconnect all cables inside the chassis. Remove the drive cage if needed and any remaining cables and all cards in expansion slots and place them on an anti-static surface. Leave CPU and memory in their places and remove the screws holding the motherboard to the case, and carefully remove the motherboard. Place CPU and memory on the anti-static surface.

Installing Motherboard

Check for correct voltage of SMPS for new motherboard. No conductive surface should come in contact with any metal parts of the chassis. Chassis may have elevated mounting holes that hold the board away from the case wall or standoffs which are small spacers that are between board’s and case’s mounting holes. After screwing in the screws, install the power connectors and reinstall all of the peripheral devices which were connected to the old motherboard.

Motherboard Setup

Motherboards have stickers indicating DIP switches and jumpers which are illustrated in the motherboard manual or at manufacturer’s Web site.

Depending on the board, settings can be done by jumpers or DIP switches or CMOS setup according to the speed and family of the processor, and there might also be jumpers to reset the CMOS, redirect the sound from the rear to front connectors, select the type of memory to install, and others.

Motherboard Maintenance

Maintenance involves download and install of new driver for motherboard from manufacturer’s website and replacing CMOS battery if computer does not saves BIOS configuration during reboots.
