Cannot get new build to even light up the motherboard

I am fairly new to building PC's, however, I built a PC last month and everything worked out very well. I had no issues other than I forgot to plug in the 8 pin to the CPU and after that the computer has been working great. That build was the following,
i7-7700k CPU
Asus Prime Z270-P Mobo
Corsair Hydro H60 AIO Pump
CX 750 Bronze
Corsair Vengeance 2x8 GB Ram 3200 mhz Ram
Samsung 960 evo 500 GB
Corsair Carbide Series 100R
all bought pretty much from amazon

After the success of that build, I wanted to do another one for myself personally because that was a company computer. And this is where things have went wrong. The build started with the following,
AMD Ryzen 1700 CPU
MSI B350 Tomohawk Mobo
Corsair Hydro H60 AIO Pump
Asus AMD RX 480 8GB Graphics Card
Corsair Vengeance 2x8 GB 2666 mhz Ram
Samsung 850 Pro 512 GB SSD
Corsair Carbide Series 100R Silent Edition
all bought pretty much from newegg

After I assembled everything it booted up perfectly first try with no issues. I restarted the computer 3 times to make sure it booted properly more than once. I then restarted it a fourth so that I could look at the BIOS and make sure everything was set how I wanted it. I changed the fan settings and increased RPM's because the CPU was idle at 40c and then I changed the ram to allow OC of 2666 mhz. After that everything went down hill. The motherboard gave me the option to save settings and restart. Upon restarting the fans would turn on and it would not post. There were two red LED's one next to "CPU" and the other "DRAM." This is how I tried to diagnose the issue:

1.) Uninstalled and reinstalled the CPU and made sure the arrow was going to the right place. Tried to boot, still same issue.
2.) Uninstalled and reinstalled both rams in A2 and B2 slots. Tried to boot, still same issue.
3.) Installed only the A2 Ram. Tried to boot, still same issue.
4.) Then tried to take off the Corsair pump and install a standard fan.

After the fourth attempt, things got worse. None of the LED 's would light up on the motherboard at all. To specify, I am talking about all of the LED's on the motherboard, not just the CPU and DRAM LED's. Along with this, the all of the fans stopped working as well. The led for the graphics was on though. So after searching I came across this guide, http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems. I did every single step in that. The only one I was unsure about was stand offs for the mother board. I didn't see anything like that that came with the case. I assume I didn't need them because my motherboard doesn't sit right on the case. After doing all that and trying to reboot all those times, i noticed that the LED on the graphics wasn't lit anymore. At this point I assumed that I fried the motherboard somehow, or i screwed it up because I didn't have an anti static device. So I went to the electronic store and bought an Asus x370 Prime-Pro motherboard. Got back home installed it and the same issue persists. Then I decided, well since I had the LED on the graphics card then it must be a PSU issue. I then went to the hardware store and bought a new Corsair CX750M PSU and still the same issue persists. I really have no idea as to what to do at this point.

Thank you very much for any help that you can provide to me and if I wasn't clear enough just let me know where and I will specify.

Once again thanks!

Remove the battery on the MSI to clear the CMOS settings. Then see if it does something

Depending on what BIOS is on the ASUS (look at the sticker on the mobo). It needs BIOS 0502 to support that Ryzen

The last 4 numbers on the sticker, is the BIOS thats on it

lol I initially thought you were having issues with your RGB LEDs... (to be honest that made me angry).

Yeah reset your bios settings using the reset jumper. Try again.

That generally should be your first troubleshooting step before removing hardware and so on.

I reinstalled the MSI mobo, cpu, 1 stick of ram, the AIO pump, and the mobo turned on finally. However, it no longer posts. I was getting three red LED's on the mobo. After hit the power switch the CPU LED pops up for about 5 seconds then turns off, then the GPU LED towards the top of the board and the BOOT LED comes on and stay on. I thought maybe I need the graphics card card installed so I put that in and I get the same codes. I'm thinking the CPU might be defective because it wouldn't even get to this point on the ASUS mobo. What do you think?

Thanks again for the assistance!

Sorry, I forgot to mention I put the MSI B350 back in like you said to do. I'm going to return the Asus mobo because you were right its the wrong BIOS info. But with that, would you say it is probably coming down to the CPU or the mobo?
