VIA 693/693A AT MAINBOARD
INTRODUCTION
1-5
Winbond W83783S (U2) is designed on the board to monitor hardware healthy
status like system voltage, system temperature, and cooling fans. When the CPU is
over heated, the system BIOS will tell the system board to give a series of beeping
alarm and then slow down the CPU speed so that you can take proper action to
prevent damage to your system. When you hear the beeping alarm, be sure to turn
the power off and open the chassis immediately, check on the cooling fans
(especially the CPU cooling fan ) to see whether it is working properly or not. If
you don’t know how to handle it, send the PC system to your dealer for technical
support.
This mainboard also provides the hardware monitoring program so that you can
monitor the healthy status of your PC system. When you find there is the Winbond
W83783S (U2) is installed on the board, you can run the hardware monitoring
program and then it will inform you the system status all the time.
