Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
•
Unplug the power cord from the wall socket before touching any component.
•
Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, to avoid damaging them due
to static electricity.
•
Before you install or remove any component, ensure that the ATX power supply is
switched off or the power cord is detached from the power supply. Failure to do so
may cause severe damage to the motherboard, peripherals, or components.
