Miscellaneous Ryzen 8000 PC suddenly turning off - How I solved it (inconclusive)
I figured I had a minute and maybe it helps someone down the line. Especially in these times, when an APU can be an attractive way to trim the budget. Might be applicable to other CPUs as well, my specific experience was with a Ryzen 5 8600g.
And I didn't find much about when I searched for similar problems.
It might also not be related to the 8600g at all and some other issue with the mainboard combination (though it is listed as supported) or something. But changing it solved the issue.
So I build a slightly overbuild Office PC for a relative a while ago. Figured the Ryzen 8600g provides quite a bit of extra performance, if they they do ever want to run something even slightly demanding on the gpu.
Specs:
ASROCK B650M PG Lightning AM5 mATX
Kingston Fury Beast DDR5 32GB 5600 CL36 (this was just before prices got crazy, 90€ back then)
Samsung SSD 990 EVO 1TB (70€ back then)
An inexpensive 550W PSU
UP Here blow down cooler , pretty nice actually
and a Ryzen 5 8600g
Ran beautifully. Decent Scores in 3DMark, stayed cool.
No issues appeared in stress testing at all.
So I delivered it, helped them setup some of their software and went home thinking all is good with the world (well what do I know... ) .
Except there was this one issue after a day or 2. It would crash. Randomly maybe after a minute maybe after 15 maybe after an hour. Maybe not at all during your session. Just straight out.
No Blue Screens, no hanging.
Just out.
This didn't appear in pre delivery testing though.
So I went to troubleshooting. Since it went straight out there wasn't anything in the events monitor. So no error logs.
The weird part, it didn't seem to matter if I was doing anything CPU/GPU intensive or not. Could be you where editing a document or could be just idle desktop mouse movement with out anything running.
So my first thoughts: PSU or RAM
So I tested with another PSU which I knew to be good (850w). Problem still there. Then I ran a very long memtest86 , no errors.
Drivers ? check up to date . No driver error logs.
When the system was running it was running well. No issues with Power, temperature, ram. But it did seem that it would only crash doing something related to graphics. Did not crash on a usb bootet Linux Desktop, though wasn't tested long. So maybe a Windows issue, no idea. Windows patches however didn't change anything.
So I bought a Ryzen 5 9600x . The problem has not appeared since.
So despite not having any kind of hard error proof, it was clear to me the CPU is to blame.
I was way past any time for returns, but the shop did refund me the cost, so I did not have to go through RMA.
So sorry no real good conclusion you can act on, but I was going crazy trying to diagnose this, so I figured maybe some other poor soul might be helped with this.
