I believe this issue first started during mid-December, around the time of a major update.
Since then, I've been experiencing random, sudden reboots every 1 or 2 days. No warnings, no BSOD, the screen just goes black and the computer reboots.
Never had it more than once in a single day.
I assumed this was due to a faulty power supply, so I replaced it, but the problem persists.
While I don't get a BSOD, it does produce a minidump, which leads me to believe it's the fault of Windows, rather than a faulty motherboard perhaps.
Minidump: click here analysis: click hereclick here haven't made any recent physical changes to my PC (besides the power supply, which turned out not to be faulty).
I've run Windows Memory Diagnostic and it found no errors.
I also ran a CPU stress test using prime95 for 4 hours and encountered no errors/reboots.
Whenever there is a major Windows 10 update in the past, I've noticed a lot of settings are reverted and certain drivers need to be reinstalled. This has led me to believe that what I'm experiencing is a software fault, rather than a hardware fault.
Of course that doesn't rule out the possibility of a faulty bit of hardware, maybe the motherboard.
My new HP Pavillion PC is doing exactly the same as you describe, and I was thinking to return it under warranty. I've had it about four weeks, and during that time it's had a couple of major (timewise) Windows 10 updates apart from the initial one when I first set it up.
The only thing I think I've noticed is that it only seems to happen when I have more than one program open, and it always seems to happen when I left-click the mouse. Shut downs are never more than once a day, and the PC always restarts automatically.
I'd be interested to hear any theories about what's going on, before I start the returns process.

StLucia, it would help if you can do what the original poster did, so head over to the C:\Windows\minidump folder and upload two or three of the most recent files to a file-sharing website. When that's done post the link here and I'll have a look at them.
By the way, the OP's minidump file returned a conclusion of "hardware error" when I analysed it. That can be caused by zillions of things unfortunately. Most of the time though the specific culprit can be identified so it's worth you trying what I suggested.
Mysteriously my reboot problem hasn't reoccurred for almost 4 days, when it's been almost consistently rebooting every 1-2 days for a month, so I can't provide any more minidumps. For some reason the old minidumps get erased/replaced whenever a new one is made.
