Computer Blue Screens or Shut Offs when I lock it

I have the AMD radeon control panel which says 18.5.1

They push out new updates pretty often and I try and stay up to date.

Thanks. And another once: Any traces of DMP files under \Windows\LiveKernelReports?

The reason I chimed in: I have the same GPU card (HP-branded, revamped as R9 380) and cannot say that the driver I use is stable as I see 141 bug checks errors when PC is left idle (but with users logged off), that are registered there as kernel events referencing the driver you mentioned earlier. But OS always recovers and does not crash.

But HP-supplied driver I use is 6-7 months' old (17.7?), although the MS-supplied one is even older:

Microsoft Update Catalog

Might be barking the wrong tree but always worth checking.

There is a post mortem dump file in that folder Attachment 195144

Are you saying the old driver is giving errors, but doesn't cause BSOD or the newest drivers is the one giving errors?

The former: Old driver giving these errors.

Cannot install correctly the newest driver (via AMD) as GPU is marked then as R9 200 (incorrectly) and Windows 10 on its own changes this driver back to the one that Microsoft supplies so it's marked back as R9 380. I decided to use HP-supplied one (17.7) and await developments.

It does not look like you had any recent events since Feb earlier this year so perhaps not related - still worth checking what these DMP files contain though IMHO.

Got another one today. Locked the computer to go get coffee and when I came back 10 minutes later it had BSOD and restarted. Attachment 195278

Got another one yesterday when I left work. Attachment 195353

Whenever there is a BSOD please also post a memory dump for troubleshooting.
Open file explorer > this PC > C: > in the right upper corner search for C:\windows\memory.dmp > zip > post a one drive or drop box share link.
The latest memory dump file was approximately 1.6 GB so it may take some time to upload and download.

That file is 16 gb. I can put it into my google drive, but it'd probably take a while

That is too large to upload and download.
For each BSOD check the size of the memory.dmp and if < 2 GB > zip > post a one drive or drop box share link

I've now had a chance to look at your recent BSOD events. They were both SYSTEM_SERVICE_EXCEPTION bug checks; these have a value of 0x0000003B. This indicates that an exception happened while executing a routine that transitions from non-privileged code to privileged code. The crash dumps do not show what might be causing this.

I've looked through your event logs to see if I can see what might be happening but it is not clear. In one instance Chrome was running and in the other windows was updating. In both cases it looks like the registry was being updated. Please run a disk check and then a system file check to make sure there is no file corruption.
