What are the basic steps taken for a computer mother board Maintenance?

Power supply must be running, than we clean the motherboard by blower machine. Check the Ram & it's slote, test cooling fan. We also followed the buzzer's beep. When the buzzer's long beep once, then Ram fault. Change Ram. The buzzer's beep twice but no display, then graphics card problem. Extra graphics card are needed. Install the graphics card in PCI slote.

when cleaning the motherboard from dust, dirt, or hair is to use compressed air. When using compressed air, hold it in the upright position to prevent any of the chemicals from coming out of the container, which may damage or corrode the motherboard or other components. Also, ensure when using compressed air that you always blow the dust or dirt away from the motherboard or out of the case.
