Hey Matt, sorry I didn't respond immediately, had a water pump failure on my PC, so I had to replace before I could use my system again (which required a whole tear down of the machine to install).  

Has the CPU fan ever turned on?  

Please remove the GPU and all ram, make sure the 8 pin CPU power cable and 24 pin mobo cable is properly secured.  Ensure the CPU fan is plugged into the CPU header on the board.  

Let me know what happens.

You were right TooQik, the motherboard wasn't properly secured in. Now it is. If it comes to it, I'll try the cardboard test.

But I have an important update, which is that I just realized that although the video card lights up and the case fan spins, the cpu fan does not spin.

I am definitely afraid that I might have damaged the board in some way, but could this also be a power related issue?

As this is your first PC, there are some things you need to do to ensure the safety of your hardware. 1 - You need to have your motherboard grounded properly. All the screw holes that connect to standoffs on your tower are there to both secure and ground your motherboard as well as keep the aluminum case from acting as a jumper from header to header on the board. 2 - It's common practice to unplug the cables from the PSU to the board and GPU before pulling them out to avoid any potential issues with voltage while the device is intended to be off. What Power supply do you have? How many watts? Also, you put your GPU in the second PCI-E slot, I'd recommend running the GPU in the top (closest to the CPU) PCI slot as generally this is the only slot that supports up to 16x (the one you had the card in is an 8x, so half the bandwidth). Do you have any speakers for the board? Something that goes right into the board to give you a beep at post when booting?ï»?/span>

Matt, looking at your video it appears as though you have the motherboard sitting loosely on the PC case. Are you able to confirm whether you have insulated the motherboard from the motherboard standoffs you screw the motherboard to? If not, then you could be shorting out the motherboard on the PC case.

I know it's a pain, but it would be better to take the motherboard out entirely and place it on a non conductive surface, I usually use cardboard, to bench test it.

Also, have you tried the video card in both PCIe slots? If not, try it. If the video card works in one and not the other, then you have a PCIe slot issue and need to RMA the motherboard. If it doens't work in either then you most likely have a faulty video card but would still recommend trying it in another PC even if it means taking it to a retailer to see if they can test it for you.

Thanks, I don't have easy access to another video card but at least you're giving me hope that there are more things I can try.

I also purchased a BIOS testing kit, since I'm pretty desperate. I have never used anything like this before... and it's not working at all. I posted a 3-minute video to help show the problem:

https://www.youtube.com/watch?v=_uJCrnASSs0

Looking back I'm realizing I may be totally misunderstanding the whole BIOS thing. I have always been a mac user and this is actually my first PC, so there are a lot of basic concepts I'm still trying to learn. After looking it up, I found out that the OS I installed (Windows 10) actually cannot load BIOS unless you perform a special kind of shutdown and restart from the Desktop. 

So is it even possible to load BIOS on this motherboard? I'm not entirely sure. One theory I had was that maybe the OS is installed only in the SSD. SO I detached it (after I took the video) and redid the same test with the BIOS testing kit with no SSD attached. Nothing, still no power going to the BIOS testing kit.


So I think the first step for me is to have a solid understanding of why this is happening. Some of the advice I've gotten so far has been related to my video card, but as far as I know, the video card doesn't even matter. When I first built this PC, before I installed Windows 10, I saw a config screen by turning the PC on with no video card and the HDMI connected directly to the board. All I'm worried about right now is being able to get to this point again (which I'm assuming is BIOS?) and then I'll start worrying about the video card again. 

Again I'm a total beginner so please correct me if anything I'm saying doesn't make sense.

I have a busy schedule so sorry I can't report back every day. Thanks so much.

After reading an online tutorial on how to troubleshoot motherboard boot issues, I decided to try resetting the motherboard to factory settings. I pulled out the CMOS battery and waited 10 minutes before putting it back in. Unfortunately, it did not help.

I want to share another observation I made, but take it with a grain of salt because its based on a fuzzy memory from before the computer's video stopped showing. I thought that when I used to press the on button on the computer case, there would be a brief "whoosh" like a little surge of power, which you could hear because the fan would suddenly speed up a lot and then relax after a second. I might be making this up, but I think I noticed this also stopped right around when video stopped working. If this doesn't sound familiar to anyone lets just say I made it up, but otherwise, maybe its a clue to whats happening.

Sorry I'm not very knowledgeable about the terminology but I dont think there is an integrated GPU and never meant to say that. I should have listed the parts I'm using in the first post.

Here they are:

CPU: Ryzen 7 1700x 3.4 GHz 8 Core AM4 Boxed Processor
Memory: Evo Potenza 16GB 2x 8GB DDR4-2400 PC4-19200 CL 16 Diel Channel Desktop Memory Kit
Video Card: Radeon RX-570 ROG Overclocked 4GB GDDR5 Video Card
Motherboard: AB350M Pro4 AM4 mATX AMD Motherboard
Storage: 240 GB NAND SATA 3.0.6.0 GB/s 2.5" Internal SSD
Fan: Hyper 212 EVO Universal CPU Cooler

Indeed, no GPU no post unless you have a 2200g or 2400g Ryzen CPU or an A-Series APU.

If you are describe your situation inaccurately it makes it very difficult to help you.
