PC crashing at random and CPU LED turns on

I’ve been battling error codes for the last couple weeks and I thought I finally got to the bottom of it. I ended up crashing again and noticed the red CPU light come on on my motherboard. (My pc stays on but my monitors shut off) I’ve been trying to play Red Dead 2 but now it’s just become a crashing point so I can figure it out but now I’m lost. About 6 months ago I bought a new PSU because my old one died and I guess since then I hadn’t tried to play any games it’s been crashing on.

I’ve got an Msi x470 gaming pro Msi rtx 4070 Ryzen 9 5900x 2x gskill trident z neo 16bg 3200mhz Corsair rm850x fully modular atx psu My internals aren’t overheating and my cpu is hovering around 55-65C and I can’t tell what’s making it crash Thanks for the help
