Troubleshooting at First Start

Boot-up Issues
The system does not power-up, no beeping sound heard and the CPU fan
does not turn on.
1. Check if the power cord is plugged in the power source.
2. Check if the power is connected to the M/B. (both the ATX 12V and
the ATX connector)
3. Check if the cable of the case power button is connected to the M/B
power button connector (see connectors and plug-ins in this manual
for more info).
4. Make sure the power supply is not defective. Change the power
supply. The minimum should be 350 watts for a minimally loaded
system or 400 watt for a fully loaded system.
5. Remove the M/B from the case and test the system. The M/B might
be shorted to the case.
The system powers up, no video, no beeping sound heard, but the CPU
fan is turning.
1. Clear the CMOS RAM. (JP5 connector, see the manual for more
info on how to clear the CMOS).
2. Check all the jumper settings on the M/B.
3. Check if the CPU is ok by using another CPU (check the manual for
CPU supported on this M/B).
4. Check if the power supply is ok. The minimum should be 350 watts
for a minimally loaded system or 400 watt for a fully loaded system.
5. Make sure the CPU fan is connected to CPUFAN1 connector.
6. Remove the M/B from the case and test the system. The M/B might
be shorted to the case.
