I'm troubleshooting my little sister's PC which has an Intel i7 6700 processor and a Vega 64 GPU. She's experiencing crashes when trying to play Roblox. I've updated all the drivers and ran Heaven benchmarks without any problems, but when I tested Superposition, the whole PC crashed and restarted in less than 20 seconds on 1080p extreme settings. I'm using a Deepcool DA600 600W power supply. I've run OCCT to stress both the CPU and GPU simultaneously for five minutes without any crashes. I had been using this GPU in my own setup and was playing VR games just last night without issues. Any ideas on what I should do to fix this?

What’s the exact model of your power supply? The Vega 64 is known to be quite power-hungry and can run hot. Just checking!

It's a Deepcool DA600.
