Heya Dave,
Here is the error I’m seeing in the Windows Error Reporting from the DxDiag that was listed your post:
+++ WER8 +++:
Fault bucket 1429670782235538746, type 5
Event Name: D3DDRED2
Response: Not available
Cab Id: 0
Problem signature:
P1: VEN_10DE
P2: 30.0.14.7212
P3: 0x887A0006
P4: 7
P5: D2R.exe
Might be good to try using DDU to uninstall the graphics drivers then reinstall a fresh set from the manufacturer website. Your hardware looks great so I’m hopeful that’s all it is.
Let us know how things go. Cheers!
