The system turns on for some seconds then shutdown by itself.
1. Check if the CPU fan is connected to the CPUFAN1 connector.
2. The CPU might be overheating. Check the CPU FAN if it is defective or see if the CPU fan
is in contact with the CPU.
3. Clear the CMOS ram. (JP5 connector, see this Quick start guide for more info on how to
clear the CMOS).
4. Make sure the power supply you have in your system supports the M/B specification.
Example. If you have a P4 M/B, you need to use a P4 power supply. (ATX 12V compliant)
5. If you already checked the power supply specification, change the power supply it might
be defective or to low for your configuration. The minimum is 350 watts.
When I boot up my system, everything works fine, it sees my CPU and memory,

2. If it still has the problem, remove all other add-on cards except the video card see if it boots

During Boot-up, my computer says CMOS memory Checksum error. What is the

1. Clear CMOS memory.
2. Re-flash BIOS.
3. Changed the CMOS battery.
4. The BIOS chip might be failing.
Redo your CMOS setup settings. If your battery is empty the error will occur more frequently. You will
need to replace the battery in this case. If the problem persists, reflash the BIOS. If all fails your BIOS
chip is failing and needs to be replaced.
Stability Issue
My system intermittently locks up, very unstable
1. Check the CPU Temp, it might be overheating. Change the CPU FAN. (Check in the
health monitor setup menu what your CPU temperature is)
2. Do not overclock your CPU
3. Check the specification of the memory module, maybe the M/B does not support it.
4. Go to BIOS setup and load fail safe settings. Please check if the system performance in
