Miner keeps crashing after 30 minutes to 3 hours

Prior to adding my 3 most recent GPUs I have had no issues with mining, but ever since then my miner will stop and freeze (kinda) after 30 minutes to 6 hours of use. The text on the miner will start flickering and the computer will be unresponsive to any commands, I usually have to force a shutdown or reboot. Linked below is a video of the screen when this is happening.

Does anybody have any idea what the issue could be?

Motherboard: ASUS Z390-P
hiveOS kernel: 5.4.0-hiveos #108
hiveOS version: 0.6-204@210608
GPUs before crashes: RTX 3070, RTX 3080
GPUs added: Radeon 6700XT, 2x RTX 3070Ti
