I'm new to PC gaming. And I just recently bought a NZXT pc. Its got a Ryzen 5 2600 , RTX 2060, 2 G.SKILL Ripjaws 8gb ram, and a Cryorig cooling fan. I recently went on a week long vacation and my pc was perfectly fine. But, I just got back 2 days ago, and when i'm playing Forza Horizon 4 or Rainbow Six Siege, my pc will randomly shut off. I don't think it's overheating because I am in a constant 64 degrees room and I watch the temp on Core Temp. And I can't figure out why it's doing this. Help?
