The PC AlertTM 4 is a utility you can find in the CD-ROM disk. The utility
is just like your PC doctor that can detect the following PC hardware status
during real time operation:
Ømonitor CPU & system temperatures
Ømonitor fan speeds
Ømonitor system voltages
If one of the items above is abnormal, the program main screen will be
immediately shown on the screen, with the abnormal item highlighted in red.
This will continue to be shown until the condition returns to the normal status.
Users can use the Adjusting Keys to change the minimum and maximum
threshold of each item for the system to send out a warning message. Click

Hardware Setup
Central Processing Unit: CPU
The mainboard supports AMD®Athlon™, Athlon™ XP and Duron™
processors in the 462 pin package. The mainboard uses a CPU socket called
Socket A for easy CPU installation. When you are installing the CPU, make
sure the CPU has a heat sink and a cooling fan attached on the top to
prevent overheating. If you do not find the heat sink and cooling fan, contact
your dealer to purchase and install them before turning on the computer.
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Look for the cut edge. The cut
edge should point towards the
lever pivot. The CPU will
only fit in the correct
orientation.
3. Hold the CPU down firmly,
and then close the lever to
complete the installation.

Overheating will seriously damage the CPU and system, al-
ways make sure the cooling fan can work properly to protect
the CPU from overheating.
