After assembling the PC for the first time you may experience some start up problems.
Before calling for technical support or returning for warranty, this chapter may help to
address some of the common questions using some basic troubleshooting tips.
a) System does not power up and the fans are not running.
1.Disassemble the PC to remove the VGA adaptor card, DDR memory, LAN, USB and
other peripherals including keyboard and mouse. Leave only the motherboard, CPU with
CPU cooler and power supply connected. Turn on again to see if the CPU and power
supply fans are running.
2. Make sure to remove any unused screws or other metal objects such as screwdrivers
from the inside PC case. This is to prevent damage from short circuit.
3. Check the CPU FAN connector is connected to the motherboard.
4. For Intel platforms check the pins on the CPU socket for damage or bent. A bent pin
may cause failure to boot and sometimes permanent damage from short circuit.
5. Check the 12V power connector is connected to the motherboard.
6. Check that the 12V power & ATX connectors are fully inserted into the motherboard
connectors. Make sure the latches of the cable and connector are locked into place.
b) Power is on, fans are running but there is no display
1. Make sure the monitor is turned on and the monitor cable is properly connected to the
PC.
2. Check the VGA adapter card (if applicable) is inserted properly.
3. Listen for beep sounds. If you are using internal PC speaker make sure it is connected.
