Start up problems during assembly

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. Check that the 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.
