  2. 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:
    "No POST", "system won't boot", and "no video output" troubleshooting checklist

    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
