Hello all! This is my first forum post on here so obviously I'm a bit desperate at this point. I've been working with computers for about 4 years and have no clue what this issue could be. Since I have no spare parts to test it with except a second PSU, I've come here to see if anyone has experienced a similar issue and/or knows what the problem is.
Basically I was moving my parts from one case to another and during the process I must have screwed something up. The computer will "start running" but won't boot into Windows or show anything on-screen.
Here's what occurs with PSU #1; a 480watt power supply: I plug in the computer to a monitor and outlet and press the power button. Everything in the computer begins to run; the processor fan, video card fan, case fans+lights, power supply (obviously), and I believe I hear my hard drives starting up. My monitor detects nothing (I've tried it with multiple monitor cables as well) and when I try to press/hold the power button to turn it back off, it does not respond.

With PSU #2; a 500watt power supply: I plug everything in and press the power button. The PSU makes a short ticking noise (one tick) and does nothing else. If I hold the power button it ticks over and over with short intervals.

Things I've tried so far:
Boot without graphics card using integrated graphics
Boot with graphics card installed but on integrated graphics
Switching back to the original case
Securing the stand-offs and triple-checking them
Boot with only one stick of RAM (tried with both sticks in every possible combination)
Boot with two different power supplies in two different cases
Boot with minimal possible parts in computer
Boot with only one hard drive connected (tried with two different ones)
Uninstall and reinstall CPU
Different outlets and different power cables
Let it stand while running for 10 minutes
Different monitors with different monitor cables
Internal speaker test with minimal amount of parts
Internal speaker test with all parts

In the case:
500 and 480 watt power supplies (don't have exact model names)

I'll be paying very close attention to this thread to answer any questions you may have to help figure this out. This is my personal computer and a very large part of my everyday life so I hope this can be solved soon! Thanks!

EDIT: Added links for the hardware I could
EDIT 2: Got PSU #2 to react exactly as PSU #1 does. Not sure what I changed this time. Also tried booting with the internal speaker and got no beeps (either with bare minimum or with everything)

EDIT 3: PROBLEM SOLVED! In the end I'm not quite sure what it was. I ended up running it with the bare minimum with an internal speaker and slowly adding parts; booting inbetween. In the end it just worked, I have no idea how it was solved. Nobody left any responses, but thank you to anyone who looked at the thread and at least spent their time to try and figure it out! Was probably just a simple mistake I made every time I rebuilt it (about 7 in a row, jeez).

tl;dr/moral of the story: Keep trying random shit and never quit it.
 
Solution
Post your complete and detailed build - OS, PSU, GPU, RAM.

Go through Tom's checklist - http://www.tomshardware.com/forum/261145-31-perform-ste... - CAREFULLY!!!

If you didn't fix it, you need to start replacing bits.

That's why you need to post your complete and detailed build.

eg we can't tell if you have a good or bad quality power supply if you say "500 and 480 watt power supplies (don't have exact model names)"
