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.

• Use a grounded wrist strap or touch a safely grounded object or to

a metal object, such as the power supply case, before handling

components to avoid damaging them due to static electricity

• Hold components by the edges to avoid touching the ICs on them.

• Whenever you uninstall any component, place it on a grounded

antistatic pad or in the bag that came with the component.

•Before you install or remove any component, ensureBefore you install or remove any component, ensure
