I started to use this computer only a few months ago, and in that time, i have found that on occasions the computer shuts down unexpectedly during any prolonged absence.
On return, a simple re-boot brings the computer back to normality, with an error message stating the computer shutdown unexpectedly. Microsoft offers the option to find a solution, but this turns out to be negative.
Looking in the Events Log, there appears to be a lot of error or warnings, throughout every day. Today for instance, 3 error, 5 warnings have already appeared in the Event Log since about 9.50AM. One usual warning seems to have a tie with Microsoft Office 2010, with the report CVHSVC Event ID 100, Task C Client...
Having done an internet search, I seem to have various solutions, including overheating, which is leading to further confusion.
Does anyone have a possible solution or checking procedure, that might find any problems, that are appearing in the Events Log, or the possible reason for the unexpected shut downs.
As I mentioned earlier, the computer shuts down unexpectedly. No hibernation.
It doesn't do this all the time, only occasionally.
Checking the power options, the list seems to suggest (1) Turn off display 10 mins (2) Put computer to sleep 30 mins. I have made no adjustment to these figures since commissioning the computer. Microsoft had already pre-set these figures.
Neither of these options seem to apply, because the computer completely shuts down, then requires a reboot. On reboot Windows give the option on how to restart the computer, which I leave to restart 'Normally'.
