I'll try to write this as clutter free as possible, sorry if it becomes a massive wall of text.
My set up:
Processor: Intel Core i7-2600K
OS: Windows 7 Home Premium x64
GPU: NVIDIA GTX680
RAM: 16GB (4*4GB)
PSU: 1200W (can't remember model at work)
What I did:
I tried to install a new 1TB HDD in my PC yesterday (My third HD), I removed the side window on my tower and connected up the power supply and the SATA cable to the motherboard and set put the PC back together. I turned on the PC and it "runs" but the monitors don't pick up the computer and the keyboard and mouse seem to be dead (no lights nothing).
First attempt at fixing:
I remove the new HD because I think I may have exceeded the max power supply, but I think this is unlikely.
After some research I find out that the computer is failing the POST test (Power-On Self-Test) by not beeping once on startup. I remove the new HDD and try turning on the computer, the POST test still fails.
I screwed up an overclock years ago on my PC and reset the CMOS to fix it. I tried it now and POST test still fails.
I then disconnect my GPU (move the DVI cable to to MOBO from the GPU), my second hard-drive (call it HD2), the fans, the LED lights, my CD drive and only leave my primary hard-drive (call it HD1) after removing all power cables and SATA connections as at this point I think I may have connected them all wrong:
Results 1
I remove the lights and try where I was before them, POST test fails and no start up. I try CMOS reset again, nothing happens.
Second attempt at fixing:
At this point I'm really confused and annoyed so I decide to start from scratch again. I also perform multiple shut downs to test for consistency:
(Note: "Base" is PSU, CPU, RAM & MOBO)
Results 2
I decide not to connect the CD Drive and the LED Lights as I'm too afraid the POST test will fail and I'll have to remove and reconnect everything one thing at a time again.
Conclusion:
My results are too vague but I think the PSU is the issue but it could also be the MOBO and possibly, but unlikely, the GPU.
I'm just leaving my computer how it is for the time being, at least I can run it, it's just a challenge to turn on.

Questions:
What is wrong with my computer and how do I fix it?
What caused the problem?
How can I tell with certainty which component is causing these issues?
