2.2 Pre-installation Precautions
Take note of the follow ing precautions before you install motherboard components or
change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any components.
2. To avoid damaging the motherboard’s components due to static electricity, NEVER
place your motherboard directly on the carpet or the like. Also remember to use a
grounded wrist strap or touch a safety grounded object before you handle the compo-
nents.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded anti-static pad or in
the bag that comes with the component.
5. When placing screws into the screw holes to secure the motherboard to the chassis,
please do not over-tighten the screws! Doing so may damage the motherboard.
Before you install or remove any component, ensure that th e power is switched o or the
power cord is detached from the power supply. Failure to do so may c ause severe damage to
the motherboard, peripherals, and/or components.

2.3 Installing the CPU and Heatsink
1. Before you insert the CPU into the socket, please check if the PnP cap is on the socket ,
if the CPU sur face is unclean, or if there are any bent pins in the socket . Do not force to
inser t the CPU into the socket if above situation is found . Otherwise, the CPU will be
seriously damaged.
2. Unplug all power c ables before ins talling the CPU.
