PC Start-up Failure

[GINGANINJA323]

Recently, I had issues involving the Front Panel on my new case, a Corsair Carbide Series Air 540, which has been resolved with a new rocker switch. However, now the PC will power on but then turns itself off within 4-5 seconds, no BIOS or any form of output to the monitor. Only the fans spin and the LEDs behave as if the computer has turned on and off correctly. Does anyone know how to fix this? Thanks in advance!

Brief Specifications:

Mobo: Asus M5A99X EVO R2.0 ATX
GPU: Asus GTX 760 2Gb
PSU: AeroCool Integrator 700W(Will be replaced soon)
CPU: AMD FX8350 @4.00GHz

Have you tried re-seating the ram in their slots? Also do you have the speaker plugged in to the motherboard, if so is it making any kind of sounds or errors?

Thanks for the reply but none of those were causing the issue. It turns out the rocker switch being used to start the PC was similar to holding the power button down, as soon as it turned on, the power was held down so the PC turned off again. Problem is sorted now. Thanks!
