RaspberryPi becoming unresponsive at random intervals (lemmy.world)

Issue Description: I have been having this issue with my raspberry pi running dietPi where it seems to lock up and I cannot SSH / access any of the services on it. The interesting part is that the interface seems to be up and I can still ping it on the local network but shows no video output. usually I get about 3-6 days before the issue appears again.

I am not really sure where to start to diagnose this issue. Any help would be appreciated!

Things Tried:

Reduced operating temp by getting a fan. I want to say this improved the length in between this issue appearing but don't really have any hard evidence.

uninstalled unused services

Limited active torrents in QbitTorrent

EDIT: Small thing to mention is that the CPU load is usually really high - like not uncommon for the load to be between 8-10 but I have seen it as high as 24.

Temporary fix:

Power cycle - everything comes up again in less than a minute.

Raspberry Pi 3B v2

OS: DietPi

Services:

Lidarr

Radarr

Sonarr

Prowlarr

Qbittorrent

Mullvad VPN - WireGaurd

SSH

I've had this happen when I had too many USB devices plugged into it. It was having power underrun, and acting unresponsive while trying to compensate. I solved it with a powered USB hub.

Edit: I've had pairing it with an off brand power brick cause the same problem, too. Apparently the 3 and later Pi really want better power quality regulation, and some of the cheapo bricks I had lying around - while providing the right Volts and Amps, didn't control the variation well enough for the modern Pi computer.

That's the weird part is that I don't have any USB devices attached. I have Ethernet, power cable, and the fan on the case has pins going to some headers.

The case did come with another power supply so maybe I'll try that and see if anything changes.
