Newly build pc keeps freezing when trying to install windows.

Also, a thing to note: I can't get into the installer at all anymore, whilst before I could get into the installer at rare moments, but now it just freezes at the windows loading animation, or loads forever, untill after a few minutes, I get a blue screen of death, with the error "Driver_pnp_watchdog" after which the pc restarts and loads the bios.

Update: I checked if secure boot and fast boot were off, and they were indeed turned off. Next I switched the video card with my old video card, and that didn't fix the issue. 

Next I tried to install ubuntu linux, and it gave errors while trying to install it. These errors were saying something about cpu being stuck, however I've searched it up and a lot of people with that error had a problem which had nothing to do with the cpu, so not very accurate. 

Next I ran memtest86 from a usb drive, to make sure that it really isn't my ram, and the first time I ran it, it froze after 2 minutes or so. The second time it completed the tests, which took 2 hours. And indeed no memory issues.

Next I hooked up the psu to my old pc (which has a different motherboard, processor and ram) and the ssd, and tried to install windows from there, and it worked no problems. So the issue isn't the psu, and it also verified again that it has nothing to do with the ssd. 

I hooked the psu and the ssd back on to the new pc, and tried to boot it (the ssd of course had windows on it now) to see if it wanted to boot, but no. After the POST, the windows loading animation comes up the screen, together with the motherboard manufactorer logo (asrock) above it, and it loads forever. So I reset the pc, and now it froze instead of loading forever. 

I basically verified that the problem is not the psu, not the memory, not the drives, not the video card. It can only be the processor or the motherboard I guess. Do you have any suggestions? My guess is returning the motherboard, because I don't think the cpu is the problem, how could it run kali linux from a usb drive no problem? And if the cpu was the problem, wouldn't it just freeze the moment the pc POSTs? I don't have the knowledge about how a bad cpu behaves, if a cpu doesn't work, it doesn't work right?

Thanks for the reply, peter. Yes, the bios was the latest version. I also tried reinstalling the iso image on the usb stick. No success. I tried a different usb stick with a windows installation image. No success either. I tried different usb ports on the motherboard and on the case. 

When I was testing different ram sticks, I also tested them individually, and in different slots.

Lastly, I don't have onboard graphics. (Ryzen r5 3600 CPU)

You could also try to turn off Secure boot and Fast Boot in the BIOS.

On a UEFI BIOS you should install it as UEFI - GPT. To Install as UEFI-GPT you MUST boot the installation USB disk as UEFI (not as Legacy)
If your using a PCIe hdd, some NVMe PCIe M.2 requires a dedicated driver, so try building windows off another hdd

Hi I'm Peter an independent advisor, sorry to hear about your problem. The first thing I would have suggested was flashing the bios which you've done. Is it the latest one on the website?

I would suggest next trying to redownload the windows 10 iso image or using the media creation tool if you haven't already done so incase the actual image you were using before on different memory sticks was corrupt.

Also try booting the system using one kit of RAM and try using on board graphics (unplug a graphics card if present)
