1. Make sure that you are using a high-quality power supply. A poor-quality power supply
may cause the system to lose the CMOS setup information. Refer to Section 1.6 for
details on recommended power supplies.
2. The external CMOS battery for your motherboard may be old. Check to verify that it
still supplies approximately 3 VDC. If it does not, replace it with a new one.If the above
steps do not fix the setup configuration problem, contact your vendor for repairs.

When the System Becomes Unstable

A. If the system becomes unstable during or after OS installation, check the following:
1. BIOS support: Make sure that you have the latest BIOS installed in your system.
2. Memory support: Make sure that the memory modules are supported by testing the
modules using memtest86 or a similar utility.
Note: Click on the Tested Memory List link on the motherboard product page to see
a list of supported memory.
3. HDD support: Make sure that all hard disk drives (HDDs) work properly. Replace the
bad HDDs with good ones.
4. System cooling: Check the system cooling to make sure that all heatsink fans and CPU/
system fans, etc., work properly. Check the hardware monitoring settings in the BIOS/
SUM to make sure that the CPU and system temperatures are within the normal range.
Also check the front panel Overheat LED and make sure that it is not on.
5. Adequate power supply: Make sure that the power supply provides adequate power to
the system. Make sure that all appropriate power connectors are connected. Refer to
our website for more information on the minimum power requirements.
6. Proper software support: Make sure that the correct drivers are used.
B. If the system becomes unstable before or during OS installation, check the following:
1. Source of installation: Make sure that the devices used for installation are working
properly, including boot devices such as USB flash or media drives.
2. Cable connection: Check to make sure that all cables are connected and working
properly.
3. Use the minimum configuration for troubleshooting: Remove all unnecessary
components (starting with add-on cards first), and use the minimum configuration (but
with a memory module installed) to identify the trouble areas. Refer to the steps listed in
Section A above for proper troubleshooting procedures.
