Turneep :
Manual in my parents house sadly. I think I see the LEDs. Led 1 and 2 with two "8" patterns on them. They don't light up at all. Guess that's bad news.
I would normally say that no LEDs illuminated is a good thing, but not in this case it's a bad thing...you need them to help troubleshooting. I'd normally ask if you have a motherboard speaker like this:

At this point you have to start troubleshooting to eliminate system components. It's not a fast process, but if you don't want to waste money RMAing good parts, then it's something you have to do. I normally start by breadboarding the system:

Do this with all power connections removed from system components, preferably with the PSU removed from the case (if it works, then you'll need to remove it anyway for the breadboardng).

If your PSU starts up, then breadboard with minimum components: mobo, cpu, (1) GPU and (1) stick of memory. You're just trying to POST - not boot - so you don't really need the HDD...you can add that after you get a good post or after you ID/replace the bad part. Let us know if you're PSU passes the paperclip test and we'll move forward from there.
Unfortunately you can't try using your processors integrated graphics to eliminate the GPUs (almost a $300 mobo and no video ports to help troubleshooting...sheesh). At least you have two GPUs to test. If you pass the paperclip test, then you need to systematically swap components to see if you can get a good POST. Test with one memory stick; no POST, then try the other stick. No post with any of the memory sticks, then remove all memory and make sure you get an error on your LEDs. Move on and swap your GPUs; no POST, then completely remove and see if you get an LED error. If you get no changes in system symptoms, then you've likely narrowed it down to PSU, mobo, or CPU.
