Diagnosis...

[1982 Original]

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.
