5800x Low Utilization + Blackscreening Troubleshooting

I've been having some issues with my current build (5800x, XFX 6900xt). Issues I'm seeing encountering are low fps+stuttering compared to what this CPU/GPU should be getting in games like Valorant (averaging around 200-250 with lows below 140 at 1080p low settings)

I've also been recently getting occasional blackscreening. This specifically started occurring randomly when I began playing Hogwarts Legacy, which was the first intensive game I played on this setup. The blackscreening has also started to randomly occur when opening/closing apps and games.

I'm getting surprisingly low CPU usage when playing Val, Apex, and OW (<5% at all times) . GPU usage is normal and expected for the frames I am getting (usually between 20-60%) while playing.

Additionally, I've had instances where CPU temps and utilization have shot up randomly while opening apps or downloading updates. Below is a screenshot of my overlay while downloading an OW update.

Any ideas what might be causing this low usage/blackscreening issue?
