Below is a copy and paste from your motherboard manual.
I am providing this information as check list you can go over.

Trouble Shooting
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. 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.
a. continuous 3 short beeps : memory not detected
b. 1 long beep and 8 short beeps : VGA not detected
c) The PC suddenly shuts down while booting up.
1. The CPU may experience overheating so it will shutdown to protect itself.
Ensure the CPU fan is working properly.
2. From the BIOS setting, try to disable the Smartfan function to let the fan run at
default speed. Doing a Load Optimised Default will also disable the Smartfan.
Maintenance and care tips
Your computer, like any electrical appliance, requires proper care and maintenance.
Here are some basic PC care tips to help prolong the life of the motherboard and
keep it running as best as it can.
Start up problems after prolong use
After a prolong period of use your PC may experience start up problems again.
This may be caused by breakdown of devices connected to the motherboard such as
HDD, CPU fan, etc. The following tips may help to revive the PC or identify the
cause of failure.
1. Clear the CMOS values using the CLR_CMOS jumper. Refer to CLR_CMOS
jumper in Chapter 2 for Checking Jumper Settings in this user manual. When
completed, follow up with a Load Optimised Default in the BIOS setup.
2. Check the CPU cooler fan for dust. Long term accumulation of dust will reduce
its effectiveness to cool the processor. Clean the cooler or replace a new one if
necessary.
3. 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.
4. Remove the hard drive, optical drive or DDR memory to determine which of
these component may be at fault.
