System:

Ryzen 3600

Asrock B550 Steel Legend

Gigabyte rtx 3080 Gaming OC

DDR4 3200 32GB

Montech 750w 80+ Gold PSU

280mm AIO... temps across the board are great. CPU 50C to 60C, Mobo 40C or under, m.2 drives 35C to 45C.

No SATA drives

Symptoms:

1. Multiple times a day, the PC will slowly become unresponsive. Example: YouTube video will start buffering randomly, I can still scroll up and down, but cannot close the window. Start Menu will open, but not close. Task Manager won't open, reset button is unresponsive... over the course of 1 minute, the system becomes completely unresponsive, but mouse movement is still okay. Only a hard power off works. This problem never happens while gaming. It always occurs during light tasks like browsing or watching videos.

2. A few times a week, the PC just snaps off like power has been cut or OCP has been triggered. Never while gaming. Always during low load activities.

Things I've tried:

1. I swapped the memory for another kit I had on hand. Issue still persists.

2. I had Cable Mod extensions, I removed all of those. Issue still persists.

3. I've clean installed Windows numerous times, installed no programs beyond necessary drivers. Issue still persists.

I am leaning towards a power supply issue. I do have other units, but they are 500w, so I haven't swapped them. I have ordered another PSU.

My other suspicion is the Ryzen 3600. I've ran it at stock with PBO enabled forever. I am wondering if there has been degradation. 1.48v on light loads and 1.38v on heavy loads seems a bit high, but I've read numerous times, "this is how Ryzen 3rd gen works." I'm experimenting running it at a stock voltage and lower clock speed. I also have a new CPU ordered as well.
