I have also been having some weird issue with Windows 10. Does windows 10 have "stealth" updates that require multiple reboots to be applied? By stealth, I mean that its not telling me its applying an update.
This is what has been happening to me. Every once in a while when I boot up my computer, it will start booting until I see the windows logo and then it will reboot. Sometimes it will do this 2 or 3 times and then finally windows will load.
After this, I have shut down and rebooted windows to see if it repeats, and it does not.
Once booted, my computer will run rock solid without any issues at all.
I thought it might be a hard drive issue and downloaded some software and it says everything is fine.
Does anyone know what is causing this? I am hoping its just some kind of windows 10 stealth update and not a hardware issue. Again, it only happens every once in a while.
A related thing that might be part of the cause is that a few months ago I got an APC UPS. I have the monitoring software installed that will shutdown my computer if there is a powerfailure and my UPS will run out of power. The last time this booting thing happened, my UPS started beeping during the boot up process. Maybe it somehow is a cause?
