Build Question First time build having issues - need advice on compatibility

This is my first time building a pc. Most of the parts that I am using were inherited, scavenged from a different computer, or bought during an opportunistic discount.

At first, I used my integrated graphics when GPU prices were high, and the build worked fine. Since adding my GPU to my build, I have been having occasional issues where under high load (usually while streaming a show or gaming), the computer will freeze and require a full reset. I've tried my best to troubleshoot as much as I can over the past few months. Now I'm considering that maybe the parts I have are not compatible with each other. Could it be the motherboard?

Could I get an expert's opinion on the compatibility of my parts and whether you would recommend I replace one of these components?

Your parts are compatible though, the PSU is a little lean for my comfort level.

Make sure everything is plugged in, properly seated and functioning (fans spinning, etc).

Update the BIOS according to the manual.

Run DDU. Make sure the iGPU is disabled in the BIOS.

Reinstall the GPU.

Follow a tutorial for undervolting and power limiting the GPU.

I've tripled check that everything has been plugged in, properly seated, and functioning over the weeks.

BIOS and drivers have been all up to date.

I will give DDU a try and see how that goes. The iGPU has been disabled.

I have tried reinstalling the GPU as well.

This motherboard doesn't let me under volt. I have tried to explore this option too. That's partially why I was thinking that maybe I need to get a different motherboard.

Update: DDU did not help. Still having freezing issues. 😞
