Msi x370 no longer booting

( sorry if this is a double post, trying to do it off my phone since the computer failed)

Hello everyone! So I've gotten a ridiculous amount of help here just from feading other people's questions but now I'm stumped and need to ask one of my own.

Build:
Msi x370 mobo
Ryzen 1700x
Hyperx 4x8 gb ram
Gigabyte 1070 gpu
Windows 10

So here's the problem. Built it a few weeks ago, was using other memory and was getting issues with the EZ CPU light, but found Ram was known to have issues with this board so I got the hyperx 2133 instead. Everything booted up fine after that.

Used for a few weeks, put it through some benchmarking, stress testing, and heavy 4k editing. Operating temperature seemed fine, didn't go above 75 C even with heavy exporting (55c true temp due to that 20C adjustment.)

Last night I'm just relaxing streaming YouTube, screens go black and fans go on high speed before shutting down one it's own. Figured the computer crashed. Tried to reboot and something seemed off.

There were three dots in the upper left hand of the screen and then when the motherboard screen would post, it wasn't fitting the screen any longer. Was zoomed in. Would show Windows 10 loading screen, then just blank screens following. Would not even detect second monitor.

SO, figured it was GPU, unplugged the first Monitor and the computer came on, I signed in then it crashed again the same way. Was able to boot into safe mode and restore to a previous restore point. Same thing, unplugged one screen and it came on, crashed again. Was showing CPU light once again so I pulled out all the memory except for one stick to try to boot.

Now it won't even make it to the Windows screen, and the Boot EZ light is on. Three dots in upper left hand side of the screen when powered on, then turns to a solid non blinking line. Tried to reset CMOS, dots are still there but now the line is not.

Any thoughts? Do I need to flash new bios? I haven't done anything new, when I got the memory I set the 2133 up to 2600, and it worked just fine even through testing. I can't even get into the motherboard screen to go back down to 2133 to see if that's the issue. All the memory sticks are back in and still won't make even make it to motherboard screen

Thank you for your time, hoping you guys know what to do because I'm lost!

Thank you for the quick reply! Yep, it's the gaming Pro carbon. Tried to reset the CMOS again and no luck, same issue. Boot ez light on, screen is lit but black, only one screen seems to be detected

Not a crazy question at all! I actually believe I may have had a USB plugged in than no longer is, I am trying to plug them back in now (I have a few different ones I swap in and out when editing, so I am unsure which it might have been unfortunately). Do you think that would light the boot light?

As to the GPU, I do NOT have one I can swap in, however if I bring it back to micro center, do they have capabilities ot test such a thing? Or do I have to RMA/any way to self test?
