Brand & Model of Mobo-CPU-RAM-Graphics-PSU?

All new builds should be tested on the bencj prior to assembling in the case to avoid problems.
Bench Test
Remove EVERYTHING from the case.
Set the motherboard on a non conductive surface. The motherboard box is perfect for this. DO NOT PLACE THE MOTHERBOARD ON THE STATIC BAG! It can actually conduct electricity!
Install the CPU and heat sink.
Install 1 stick of RAM.
Install the video card and attach the power supply connection(s) to the card if your card needs it.
Connect the monitor to the video card.
Connect the power supply to the motherboard with both the 24pin main ATX Power connection and the separate 4 or 8 pin power connection.
Connect power to the power supply.
Do NOT connect ANYTHING else. Make sure you have the power connector on the CPU fan connected.
Use a small screwdriver to momentarily short the power switch connector on the motherboard. Consult your motherboard manual to find which two pins connect to your case's power switch. Then touch both pins with a screwdriver to complete the circuit and boot the system.

If all is well, it should power up and you should get a display. Then assemble the parts into the case and try again. If the system now fails to boot, you have a short in the case and need to recheck your motherboard standoffs.

If the system does not boot after this process, then you most likely have a faulty component. You'll need to swap parts, start with the power supply, until you determine what is defective.

That's a possibility and bench testing will help get you to the problem. When you remove the Mobo inspect both sides for any burned marks and look at the capacitors for any signs of swelling or leakage.

What parts did you use for the swap?
Remove all the RAM and boot. You should hear a repeated single beep from the Mobo speaker. If you hear the single repeated beep the Mobo is probably OK.

This will be the second motherboard i would have to send back. I sent one back short after my order got here due to the same problem. Any idea would could be causing them to go bad.

Considering I've worked on computers before and never had that problem i doubt its improper handling or static electricity. I did buy a refurbished PSU though starting to think that might be causing some of my problems.
