4.  The BIOS chip might be failing. 
I hear a 1-2 beeping sound and then the system shut down, what is the 
problem? 
Verify that the CPU fan is connected to the CPUFAN1 connector. 
Stability Issues 
My system intermittently locks up, very unstable 
1.  Check the CPU Temperature, your CPU might be overheating. 
Change the CPU FAN.  
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 the BIOS setup is set to Turbo/Maximum. Set 
it to normal if this is the case 
5.  Check the website for the latest BIOS update. 
6.  Check the website for FAQ’s regarding instability issues. 
7.  Change the memory module or CPU. 
8.  The power supply might not have enough wattage to support all the 
peripherals. If your system has other peripherals connected, like 
CD-RW, extra HDD, etc. disconnect them, or use a power supply 
with a higher wattage. 
My system intermittently locks up, during Windows installation. 
1.  Go to BIOS and load the “load optimized defaults”. 
2.  Check the website for any BIOS updates. 
3.  If you still have the problem, remove all other add-on cards except for 
CPU/ Memory/ onboard Video/ Hard disk. See if you can finish 
Windows installation. Then put peripherals in one by one to identify 
which one causes the lockup.
