Computer turns on and off repeatedly

[NeonFury]

Hello everyone!
Today I put my computer in the car for transportation, I ended up not needing the computer, and I never even touched it once. When I came back home, I plugged it in exactly how I had it before, pressed the power button, and the computer came on for about 2 seconds, and then turned off, before turning back on again, only to repeat the cycle.
All fans are running (CPU, GPU, PSU, Case) The lights on my case and PCI cards light up. There is no response from the monitor.
Everything is plugged in internally as far as I can tell. And I have tried moving my power cord to a different outlet, but I get the same results.
The car ride was short and smooth no big bumps, only about 10 minutes. When taking the computer out, I bumped the top slightly on a corner.
I have had this computer for over half a year now, and have not had any problems with it so far.
Specs:
PSU: Corsair RM650
CPU: i7-4790
Motherboard: Gigabyte GA-Z87X-UD3H
GPU: EVGA GTX750 1Gb
RAM: Corsair Vengeance Blue 8 GB 1600mHz
HDD: WD black 1TB
Cooler: Cooler master hyper T4
Case: NZXude T Guardian 921 RB
OS: Ubuntu 14.10
I tried to include much info as I could think of, feel free to ask me any more questions. Thank you for your help in advance!

Hi, Try re-seating the RAM modules, graphics card, check all cable connections.
