Can't find what's wrong with system that won't post

I built a system myself and was extremely careful and triple checked the wiring. It won't post though and I feel like I've tried everything I can. I replaced the RAM sticks, reset the CMOS, replaced the mobo, took out the GPU, and even tried to boot by setting up on my mobo box with just the CPU, RAM, PSU, and of course mobo. Still no display. My case didn't come with a speaker and I can't find one at my local computer store. I was going to order one but found a thread that said sometimes when the CPU is the problem the system doesn't post and won't beep. Should I buy a cheap CPU to check if that's the problem, take my system to a pro, or order a speaker online, or other?
System specs:
Intel i5 4690
Asus H97 M Plus
Fractal Design Integra R2 650W
G.Skill Sniper Series 2x4 GB DDR3
Can't remember which GPU I have, I'm at school.

I spent a decent amount of my own money on this and any help would be appreciated. If you need any other info, I'll do my best and I'm desperate at this point. Thanks
 


I went through that checklist about a week back and couldn't do the one with the speaker because I don't have one and I think I'm going to order one online today because it will be useful in the future as well.
 


Is there any way I could test my PSU to see if it was DOA? All the fans run when I try to power up so does that mean it works or does it only have enough power for the fans?
 
I just got a mobo speaker from the local computer store because the guy had one just laying around. I came home and put it on my mobo and tried to boot up and still got no display but I also got no beeps. I removed the RAM to see if it would beep to tell me that there was no RAM but that didn't happen either. I then tried a single stick of RAM in each of the slots but I still got no display. I also tried to reset the CMOS but I had no luck. At this point my system was breadboarded on the mobo box. I tried each of the integrated display ports and my GPU display ports but still nothing. I know that the RAM is working because I tried it in my desktop. I don't have an extra CPU I could test and this is already my second mobo. Is there any online support service that I can get help from or anything I can do or should I just give up?
