I’m running W7Pro on my “Big” ‘puter at home (home business CAD and finance plus the usual email and online services-—encrypted, of course) and have been experiencing some funny system shutdowns that may be related.
If I leave the box running while I’m out of the house for over a couple of hours, I come back to my login page and a note from Windoze sez “There was a Windows problem which forced a shutdown and we’ll tell you what’s going on when we figure it out” (or words to that effect).
I’ve had Update shut off and all the Win10 nagging crippled since just about the time this crap started. Don’t see or hear anything at all about either one, but I’m beginning to think that “someone” is trying to sneak some update/W10 stuff into my system and my homebrew security system is blocking enough that “they” just shut down my Windows and go away.
For now.
Jeez, I’m getting sick of this sh**.
Any more of my time gets taken away from my work to play these sillya$$ games and I may just start invoicing the bastards. At my Very Finest Premium rate.
I’ll have to say I haven’t seen update cause the kind of problem you describe, esp. since you have update turned off.
Since this happens after the computer has been on for a couple of hours, I’d look and make sure all of the fans are running properly, including the power supply fan. At the same time, make sure your computer isn’t clogged up with dust and hair and such, esp. the CPU heat exchanger. (I’m assuming from your description this is not a laptop, and though dust and over-heating is even more prevalent with laptops, the dust is harder to get out.)
Also, both semi-legitimate and malware programs running the CPU constantly at 100% can exacerbate overheating as well.
