OPERATION AND MAINTENANCE
KEEPING THE SYSTEM COO L
Airflow is critical for proper operation.
The motherboard contains many high-speed
components and they will generate heat during
operation.
Other add-on cards and hard disk
drive can also produce a lot of heat. As a result,
the temperature inside the computer system may
be very high.
These boards require cool· air to
prevent a deadly heat build-up. Be sure that all
cooling vents in the front or sides of the computer
are open and that air circulation is good. Check
the clearance at the back of the computer; the
power supply contains a fan to blow air out of the
case, make sure the fan is not blocked by cables
or papers. Don't push your computer flush against
the wall; leave it some breathing space. Heat can
destroy computer chips.
C LEANING THE "GO LDEN FINGER"
Whenever inserting an add-on card to the
motherboard, make sure that there is no dirt on
the "golden finger" of the add-on card. If not, the
contact between the "golden finger" and the slot
may be poor and thus causing the add-on cards to
work improperly. Use a pencil eraser to clean the
"golden finger" if dirt is found.
