Power To System Cycling On And Off Repeatedly Once Power Supplied

Power To System Cycling On And Off Repeatedly Once Power Supplied
So I finally got all my components and built the computer, and of course something went wrong somewhere. I plug the computer in, flip the power on the PSU, hit the power button on the case, and what do you know, it doesn't function right. For some reason everything well turn on, then immediately turn off, then turn back on again, and this cycle will continue until I turn the PSU back off. Any ideas what may be causing this issue? If it is likely component specific, I will post the component list upon request, yet I'm typing this currently from a phone and want to avoid it currently. Any thoughts would be greatly appreciated. Thank you.

Make sure the wires from your case to the mainboard are in the right places. maybe a - is were a + should be or just not in the right place.

Would that still affect it if I disconnected the power and reset cables and turned the motherboard on directly from the board? Or could one of the other case cables affect it that way?

Could you post a picture of your PC, in a way that we can see the interior of the case, with the motherboard and all.

Your issue is most likely caused by a short somewhere. Try re-installing the motherboard in the case, making sure that nothing causes a short.

Should I take a pictures of the wiring behind the board, or would a picture of the front be sufficient? What things are likely to cause a short, and is that likely to cause permanent damage to the machine?

Just the front will be fine.

Loose wires, motherboard that isn't properly grounded to the case can cause shorts. It could also be that you didn't fully insert a power cable somewhere, or that you didn't fully insert a part such as a RAM stick or video card. Double-check all the power and data cable connections.

You didn't use any type of washer between the motherboard holes and the screws that you used to secure it to the motherboard mounts on the case, right?

I didn't use any washers. If there's a short, wouldn't it just trip the PSU shutting it down until I reset the switch? If so, then why does it keep trying to turn back on? Everything is powering on, then powering off, then powering back on and continues to follow this cycle until I shut off the PSU?
Is it possible to have a short between the Silver Arrow and the RAM, and if so, how do I go about fixing that?

Here's a few pictures. Hopefully they help:

RE: Power To System Cycling On And Off Repeatedly Once Power Supplied
I can't see anything wrong looking at the pictures, so here's what I'd do:

Re-build your PC outside of the case. Put the motherboard out of the case and just set it on the foam pad that came with the box that the motherboard came in. You can also set it on the actual box. You should not have to take the PSU out of the case, just set the case near the board.

Hook up the following:
1. 24-pin main ATX power
2. 4/8-pin 12v CPU power
3. CPU cooler fan
4. 1 stick of RAM in the first slot (see motherboard guide to see which slot is the first.)
5. Video card
6. 6-pin/8-pin PCIe video card power connector(s)
there can be up to 4 of these depending on the card
7. monitor
8. mouse
9. keyboard
10. 2-pin f_panel POWER SW connector

The idea here being to rebuild the PC with the bare minimum, to see if you still get the power cycling issue. If you do, then your motherboard is most likely defective and needs to be exchanged.

On the other hand, if your PC boots fine at that point, put it in your case and add one part at a time, with booting in between each part installation. Hopefully, it will keep booting properly, but if it starts power cycling again, go a step back and make sure that the previous installed part is fully/properly inserted.
