First thing to try is loosening the Screws that hold the Motherboard to the Case. They will only need a full turn. Reconnect the Power and turn it on. If it powers up shut it down and retighten the screws. They only need to be firm.
<br><br>
Recheck your Power connections to the Motherboard, CPU and see if all of the Jumpers especially the Jumper for Clear CMOS is on the right setting.
<br><br>
Double-check all connections between the Switches and LED's on the Case to the Motherboard. Make sure that they are connected the right way.
<br><br>
Reseat any Cards.
<br><br>
Make sure that there are no loose screws or other components inside the case. These can cause shorts and other serious problems with the PC.
<br><br>
Also check the power outlet that you are connected to by plugging in something else and turning it on.
<br><br>
A faulty (PSU) Power Supply Unit can also cause it. Fluctuating power or an underpowered PSU is not good for the Motherboard. You should be running 500-600 Watts. Try another one if available or replace it.
<br><br>
<br><br>
If it's none of the above try this.
<br><br>
Carefully remove everything from the Motherboard. Remove the Motherboard and put it on an anti-static mat on a bench. Remove the Power Supply if it is a known working good one to test with. Remove the Heatsink and give it a good clean. Remove the CPU and reseat it. Reinstall the Heatsink remembering to use CPU grease. Reseat the RAM and test with one stick at a time. Connect a hard drive and the Video Card. Connect the Power supply to the Motherboard. You can use a flat blade Screwdriver to short the Power pins on the Motherboard if you haven't got a spare switch. Connect the Monitor and turn it on and see what happens. If it stars up add one Device at a time to test it. If it doesn't RMA it under warranty.

Try this it is from your Manual

by Jacky Howe In reply to See if this will help

We suggest the following three troubleshooting methods to discharge CMOS data, recover
the hardware default status, and then making the motherboard work again. There is no
need to bother returning the motherboard to where you bought it from or go through an
RMA process.
Step 1. Switch off the power supply unit and then switch it on again after one minute. If
there is no power-switch on the power supply unit, disconnect its power cord for
one minute and then reconnect.
Press and hold the <Insert> key on the keyboard, and press the power-on button
to boot up system. If it works, release the <Insert> key and hit <Del> key to enter
the BIOS setup page to apply the correct settings.
If the situation remains the same, repeat the procedures in Step 1 three times, or
try Step 2.
<br><br>
Step 2. Switch off the power supply unit or disconnect the power cord. Open the chassis
cover. Locate the CCMOS jumper near the button battery. Change the jumper
position from default 1-2 to 2-3 for one minute to discharge the CMOS data, and
then put it back to default 1-2 position.
Close the chassis and switch on the power supply unit or plug in the power cord.
Press the power-on button to boot up system. If it works, hit <Del> key to enter
the BIOS setup page to do the correct settings.
If the situation remains the same, try Step 3.
<br><br>
Step 3. The same procedure as Step 2, but while discharging the CMOS data, pull out the
ATX power connectors from motherboard and remove the button battery during
CMOS discharge.

Well you should test before fitting to the case

by OH Smeg In reply to an52v wont boot

That way if there is something wrong it's easy to pickup.

But have you repositioned the CMOS Clear Jumper? These M'Boards come with this jumper set to Clear and the system tends not to start this way. You need to move the Jumper to short Pins 1 & 2 not Pins 2 & 3.

Also what is the brand and rating of the Power Supply?

If it is insufficient the M'Board will not work.
