Computer crashes randomly while gaming

So I just upgraded my computer with a new CPU, Motherboard, PSU, and RAM.

• CPU: Ryzen 5 5600x
• MB: rog strix b-550-f gaming (wifi)
• RAM: OLOy DDR4 (2x8GB) 300MHz
• PSU: EVGA 600 BR 80+ Bronze 600W

I kept the same SSD and HDD I had in the old build and the same gtx 1060 GPU. I reinstalled windows 10 keeping my saved files. I got it up and running and tried to play Squad. As soon as I got into a game my computer restarted. No BSOD, just completely restarted. I tried again and this time it restarted before I even loaded into the main menu. I did some reading on the Squad steam forum and thought the problem might be running Razer Synapse at the same time. tried turning it off and the game ran fine, and I was able to play for a few hours. Next day I tried again and I had the same reboot issue. Tried updating my GPU drivers and a few other fixes I found on the Squad forum and I got it to work again. Next day problem repeats. Tried installing Red Dead Online and played that for a day no problems. Next day comp reboots after about an hour or two of gaming, and as of today it reboots randomly while I'm in game. Sometimes after a few minutes, sometimes hours. I never had this problem before I upgraded, in fact the games play better now (when they work) than before the CPU/MB upgrade. I've tried playing Sea of Thieves and Valorant and didn't run into problems with either.

I'm stumped. Please Help! haha
