Windows 7 PC Won't Turn On

    I built my computer in 2013 and have been using it ever since. I have only ever had to upgrade my fans and power supply. My computer cut off last night I believe when the power in my house flickered and have been unable to turn it on since. I have tried a different wall outlet. It is still receiving power because my Razer mouse and keyboard is still lit. The most I can get it to do is when I unplug the PSU and hold down the power button for approx. 30 seconds, then plug the PSU in again and press the power button. Upon doing this, the computer LED lights turn on and the fan in front of the motherboard starts to turn for a brief moment and immediately cuts off again, and pressing the power button no longer yields any results unless I repeat the aforementioned process.
    The issue I am having has never happened in the past and I feel it may be related to my power flickering but am unsure, because any time in the past that my power had gone out or flickered the computer simply cut off and would need to be turned on again. If anybody has any advice or wisdom on the subject for me it would be greatly appreciated!

    Currently my specs are:

    Rosewill 750w 80 plus psu
    Msi 970a-g43 motherboard
    Windows 7
    If any of this matters
    AMD FX 8150 processor
    Radeon HD 7850 graphics card
    8gb ram

    A quick look at what happens when I attempt to start the PC after unplugging the PSU and holding the power button for 30 seconds, then plugging it back in:

    Thanks in advance!

    Unplug everything except the keyboard and mouse and screen. No USB drives, no printers etc. Remove the GPU if there is motherboard video and use that. Then see if it powers on properly.

    If it doesn't, start swapping things like first the PSU.

    Since the case fan starts and then stops, it is either the PSU or the motherboard.
