Thank you for replying. As I was typing this, I got a new crash ON BATTERY only, so this may be worse than I thought. Grey screen first, then immediate reboot.
I checked event viewer, Windows logs, System. I see one Critical event, which reads “The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.”
It is preceded by a number of Information events about ACPI thermal zone. Immediately after the critical event, another information event “UMDF reflector is unable to connect to service control manager (SCM). This is expected during boot, when SCM has not started yet. Will retry when it starts.” It is then followed by a warning event “The driver \Driver\WUDFRd failed to load.
Device: ROOT\WINDOWSHELLOFACESOFTWAREDRIVER\0000
Status: 0xC0000365”
A few more warning events like the above follow (amid lots of information ones):
Device: HID\FRMW0005\4&94936f4&0&0000, Status: 0xC0000365
Device: USB\VID_27C6&PID_609C\UID0F10D23E_XXXX_MOC_B0, Status: 0xC0000365.
I don’t find a minidump folder (C:\Windows\minidump), even though I have had a number of BSOD during boot, during recovery. Even if I do find one eventually, I’m not that advanced to analyse such logs myself.
No crash (on battery) for the last 10 minutes while I am typing this. But I am feeling a bit hopeless and am hoping this is not a hardware issue. I will open a support ticket just in case. I’d hate it if having the FW didn’t work. On another computer, I installed Windows from the same image in a Proxmox virtual machine (i5-7500t), and no issues there.
Thanks for any further tips.
