Black Screen off and on

I built a new PC with the following parts:
ASUS X870 A motherboard
AMD 7850X CPU
XFX 9070 video card
32GB of DDR 5 6000 Ram
1300 W Sama PSU
4 TB MSI SPATIUM M470 M.2
Thermal-Right AIO
Montech King 95 Pro Case
ALIENWARE 34" OLED Display

It was working fine for about a month then my screen went black for two seconds or so and came back on. It doesn't matter what I'm doing gaming, working, or just surfing the web. After it started doing that, I had an alarm go off and it stopped without me touching it. Now it wants to reboot randomly but usually after the screen goes black. I noticed that when it comes back on that's when it reboots and at times it restarts or shuts down completely. I have updated the BIOS, the CPU sits at 40 c at idle and runs up to 65 c when playing games like Halo, Diablo, Far Cry, and so on. I noticed that the video card was sagging slightly so I purchased a brace for it and leveled it up. Is it possible that the motherboard has some sort of damage? I've tried a different PSU, RAM, and reseated the CPU. I'm at a loss where to go and if I'm missing something. I thought maybe it was heat related but everything seems to be normal.
 
What does event viewer say?
It isn't showing anything out of the ordinary. Nothing flagged for anything. :rolleyes: That's what has been driving me nuts. Before I updated to the newest driver for my video card, I removed the old one using AMD's removal tool in order to get a clean installation. That hasn't helped either. When it's running right it's scary fast compared to my old AM 4 system. I ran mem-test with no errors. I benched it with infinitybench and it didn't show any errors; in fact, it showed my system being ranked as # 12 in similar configurations. Ran Cinebench without any trouble except the screen went black and popped back on.
