Computer Powers on but then Turns off Right Away

I recently just built my PC a couple months ago with all new computer parts and everything. The problem I am having is that my computer will turn on then turns off right away. It does not stay on for even a second.

It started happening a couple weeks ago after I took my power supply out of this new computer to test my streaming computer because that one was not powering on originally and was doing that same thing my gaming PC is doing now. The things I have tried so far are buying a brand new power supply and new motherboard to see if that would work because Geek Squad at Best Buy said it is either the power supply or a faulty motherboard. Also, I've tried powering on my PC with only one graphics card in and still did the same thing.

I was wondering if it could possibly be something wrong with one of my RAM sticks and should try turning my computer on with one stick at a time to see if it will turn on and stay on?

It is just a real bummer and have no idea what the problem could be because everything is brand new and only have been using this computer since the end of December 2016 :(

Any answers or ideas would be greatly appreciated! Thank You!

Heyo FreeZyTv

I'd say you should go with your own suggestion. Just try one RAM stick at a time, if nothing happens, you can always check on your other machine if the RAM actually is faulty. Otherwise I'd say take EVERYTHING not-needed out of the PC, and try to turn it on. With this I mean:

Remove
All RAM except for 1
All CD-drives/Card readers/fan-controllers/USB-hubs
the GPU
All HDD's/SSD's
All USB devices connected
And anything you might have connected which isn't needed for the system to actually POST.

Let me hear if you find something interesting under the troubleshooting

Hrm another bit you might want to try is to attempt to boot with just the GPU and one RAM stick but do NOT have the motherboard installed into the case on the off chance some grounding is happening. That will at least get you down to motherboard, RAM, CPU, GPU, PSU as potential bad spots. Since you have the spare PSU and motherboard more than one RAM stick and GPU you should be able to figure out exactly what the issue is.
