Took apart my computer now it doesn't work. PSU Problem, or Motherboard?

So I recently bought a 212 Evo cooler because the stock cooler on my AMD CPU is loud as hell.
I built my PC around two years ago and for some reason i'm just getting around to replacing it now.
So I take everything apart, replace the panel on the back of the mobo with the new one that came with the 212. Install it, plug everything back in( psu cords that I plugged in are the one 24-pin, one to the case fan, one 4-pin to the mobo, two go to the gpu, one to ssd, one to hdd, one to cd-rom). I even plugged in the led power lights on the front, as well as the cpu fan to the mobo. If you think there's anything I may have forgot let me know.

Anyhow, after everything was together I turned it on and it didn't work. Apart from one small green led light on the bottom of the mobo no sound, no beeps, no fans, nothing. So I took it all apart again and put in the old heatsink+cooler and now it doesn't work with the original one. So i'm guessing I either damaged something(if so, what?) or i'm forgetting to plug something in.

Also I already tried taking the psu out of the case and testing it. When I connect it straight to the wall using the paperclip in the 24-pin connector it beeped and the fan whirred up straight away. Which leads me to think it isn't the psu. Also I checked if any of the pins on the processor are damaged or bent and they're all perfectly straight. Any ideas before I go and buy a new motherboard?

In case it helps my mobo is a Asus m5a97 and the power supply is a Thermaltake TR2 650W.

    Yes, reinserted the ram, it's low profile so it's out of the way of the heatsink and fits perfectly. As for the power switch connections no I haven't. Do you mean opening up the psu and making sure the cables inside are connected properly? I would assume they are since when I switched it on while testing it with the paper clip the psu turned on immdeiately.

  3. no there should be thin wires bunched together and when you open up the front of the side of the computer you will see them going in to the front of the case

    Not gonna lie, you got me excited with that one but I checked on it and I did indeed plug it in. Everything I can think of is plugged in to the right places.

  5. You could try unplugging everything and plugging it back in one by one.
