PC Alert™ III
The PC AlertTM III 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:
* monitor CPU & system temperatures
* monitor fan speed(s)
* monitor system voltage
* monitor chassis intrusion
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 users disable the warning.
Note: Items shown on PC Alert III vary depending on your system’s
status.

D-Bracket™
D-Bracket™ is an external USB bracket integrating four Diagnostic LEDs,
which use graphic signal display to help users understand their system. The
LEDs provide up to 16 combinations of signals to debug the system. The 4
LEDs can debug all problems that fail the system, such as VGA, RAM or other
failures. This special feature is very useful for the overclocking users. These
users can use the feature to detect if there are any problems or failures.
