PC I built 3 years ago

I’ve enjoyed this pc a lot.
It’s a 12700k with a chromax dual cooler installed with a noctua black fan. And white covers to match aesthetic.
Msi z370 Mobo
2x 16gb ballistix ram (I believe 5400)
2x 1tb SSD intel 970 evo
MSI – RTX 3080
6x Lian-li fans (3 stack intake on front not shown)
1000w gold+ modular psu (I believe corsair)
And a fractal design case.

I love this pc, I turned the RGB puke to solid white to match everything and give my room some ambient lighting since I keep my room so dark. Occasionally it gets this weird error where the screen turns a pixelated red and black color, restarts then is just fine. This has happened for years and I only haven’t addressed it because I haven’t found answers and it continues working just fine after restarting. There isn’t really a way to force it to happen, it’s random, but usually happens in the middle of a game regardless of how intensive the game is.
