Hello, I'm undertaking my first build, installed everything, plugged everthing in and I cannot start up the computer. Only 1 green LED light (LED1) on video card lights up.
I've followed the instructions to the best of my abillity, tried my best to discharge static electricity before touching components but I cannot boot the PC.
I attempted to install a nocuta fan to the cpu but it didn't fit which left some thermal compound on the cpu which i cleaned off with tissue.
I have tried some troubleshooting steps but some haven't worked and the rest I'm not sure what they're on about!
When I turn the power switch on at the back, the green LED lights up and nothing else happens. Nothing happens when I press/hold the start button.
SPECS
- Intel Core i5-3350P 3.1GHz Quad-Core Processor
- Stock CPU cooler
- Asus P8Z77-M PRO Micro ATX LGA1155 Motherboard
- Corsair Dominator GT 8GB (2 x 4GB) DDR3-1866 Memory
- Samsung 840 EVO 250GB 2.5" Solid State Disk
- Western Digital VelociRaptor 500GB 3.5" 10000RPM Internal Hard Drive
Asus GeForce GTX 650 Ti 1GB Video Card
- NZXT Phantom 410 (Black) ATX Mid Tower Case
- Corsair CX 500W 80+ Bronze Certified Semi-Modular ATX Power Supply
- Lite-On iHAS124-04 DVD/CD Writer
- Asus PCE-N15 802.11b/g/n PCI-Express x1 Wi-Fi Adapter
ACTION TAKEN
1. Checked all the sockets are in properly (one wasn't - the 24-pin one) but nothing changed.
2. I also tried to boot without RAM which hasn't worked.
Any help would be HUGELY appreciated, I'm a complete noob and I'm really quite worried that I may have just wasted a few hundred pound!
Thank you.

It's not possible to start a PC without RAM.
Make sure that whenever you are messing around inside the case that the PSU is unplugged from the wall socket.
Go through the installation guide/manual again. Compare what it says to how things look inside your case.
Did you reapply new thermal compund after removing it the first time when the Noctua fan didn't fit?
You said that the 24-pin connector wasn't plugged in correctly. So that would be the cause of the problem, but then when you plugged it in properly it still didn't work. Perhaps there is a chance it's still not connected properly?

The front panel connectors are at the bottom right hand corner of the motherboard. On the bottom row, the two pins on the far right are the reset pins, then there is a space to the left that is unoccupied, then another two pins. These two pins are the power switch pins. Make sure the power switch leads from the power button are plugged into these pins (orientation of the plug doesn't matter). If this is plugged in correctly, remove the plug, and use a screwdriver to short (touch together) these two pins for a quick second. Let me know what happens when you do this.

You said you cleaned off thermal compund off the CPU. There should be thermal compund on the CPU, otherwise it will be hot.
There is thermal compound on the stock cooler. The compound was only necessary for the Noctua cooler.
QUESTION
Is the ATX power supply lead part of the front panel or the PSU?

The PSU is connected to the motherboard. The motherboard is connected to the front panel. Okay so this is why I might be going wrong because, how I see it, I have the PSU connected to the graphics card, the drives and the front panel (the molex lead from the psu is connected to the front panel). And a front panel lead is connected to the motherboard (top right 8-pin)

I've checked everything and all is in order according to the vague motherboard manual. The 3 pin connector i was talking about, must've been the fan controller.
I've switched the pled - and pled + power leads like you say in your thread HiTechObessed and the only thing that changes is the video card "LED1" led does not light anymore
