PC wont boot up (No POST, No Video)

I recently installed a new Asus M5A99X Evo r2.0. The motherboard green LED lights up and the case and cpu fans spin. But there is no video when its hooked up to my monitor.

Steps that i have tried:
PERFORM THESE STEPS before posting about POST/boot/no video problems! - Systems

Made sure all connections are properly connected.

Flashing the CMOS

Tested the PSU

Followed all steps in the user manual

If there are any links that you guys can point me to or suggestions that could help it would be highly appreciated. Thank you

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??
