I’m on a custom-built windows 11 PC (Ryzen 5 x570) and have recently been having an issue where the PC will become totally unresponsive; it’s still “on”, the fans and lighting still work, but it won’t output to the display and can’t be accessed remotely (Plex and TeamViewer both consider it to be offline). The only fix for this is a hard reset. I haven’t witnessed what happens to put it in this state.
This seems to have started after trying out the Curve Optimiser built into Ryzen Master in combination with PBO, as well as using the OC scan in ASUS GPU Tweak, which also affected voltage. The CPU OC has been reverted, so that seems to leave GPU, and I’ve dealt with weird PC behaviour related to cooling/OC with the GPU before (I haven’t been able to check because I’ve been out of town).
One strange bit about it is it’s seemingly random nature. It’s never entered this state under load; it only ever happens more or less at idle (my PC is on all the time because it doubles as my Plex server)
EDIT: I’ve removed the GPU OC from ASUS GPU Tweak, which had messed with voltage. So far the hard crash hasn’t happened again, but I’ll try to remember to update this again if it does occur, for the sake of future googlers
EDIT 2: It’s been about a month now and the issue still hasn’t occurred, so I’m pretty confident it was the GPU OC
ideally, you would have an admin account separate from your user account - you could then log in on that account & create a new local user account.
if you don't have an admin account, you could boot to windows recovery, open a cmd prompt & create an account manually via the cmdline - info here https://pureinfotech.com/create-local-account-windows-11/
Got it. So it sounds like whether this is the issue or not I should be using the PC on a separate user account as a matter of course? Is that a security measure?
it's more of a test to see if the issue is software/OS related or not. creating a new user profile is basically free, and even reinstalling the OS costs nothing (if it comes to that) - I'd rather do that than buy a new PSU, GPU, etc.
