My desktop, every day shuts down in same time at 1:26 pm.
I saw running tasks, in Task Scheduler and found two tasks:
MsCtfMonitor, and;
SystemSoundsService
Do these tasks turn off my system?

Both tasks are probably not the culprit, as they do not run at scheduled times. You can verify it by disabling both and reboot. With this disabled your machine runs without following features (AFAICS):
If any of these shuts down your system this would be very unusual.
Try following:
Start a cmd.exe
in administrator mode.
Then do
schtasks /query >c:\tasks.txt
Then open c:\tasks.txt
with your favorite text editor. Skim trhough this list. You will see many blocks like following (Sorry, I am German):
Ordner: \Microsoft\Windows\Registry
Aufgabenname Nächste Laufzeit Status
======================================== ====================== ===============
RegIdleBackup 30.03.2014 00:04:27 Bereit
(Note that this example is usually not a problem. AFAICS this task backups your registry in case the master is destroyed due to a catastrophic power outage.)
The first line tells you, where you can find the task in MSC
. The second column in the other line probably shows, when the task will be started. Perhaps you can spot it there already.
Now with this overview of tasks handy, you can easily navigate in MSC
. (Without such a map you get easily lost and might miss the culprit.)
TASKSCHD.MSC
If you cannot spot it in the list from schtasks
you have to look through all the not disabled tasks in the list. Sorry, I do not know a better way.
If you cannot find anything there, you can try to disable all tasks you think you do not need.
You can try look into the event viewer, as noted by Sean. But this might involve enabling event logging of scheduled tasks. Sorry, I cannot explain how to do that if it is turned off (all machines I have access to have event logging disabled, so I think, that may be the same at others).
If this does not help, there are many other sources possible. This is too much to speculate.
Some possibilities:
Try to change your time on your computer. Does the thing depend on your local system clock? In that case it is local. If not, it is remote.
Another computer can have a scheduled task which shuts down your computer. Disconnect all network interfaces, and look if the effect still hits.
Your BIOS can have a scheduled alarm which powers down the computer. BIOS code can run outside of operating systems, so this affects the computer even if it is not booted into windows.
You can have a bad sideffect of something else running at that time. For example, I had the problem of a computer which started to shut down after logging into one of the local accounts. The problem was a bluescreen due to a corrupt user.dat
which cut the power as well (no, that is not normal behavior), so the bluescreen was shown just a fraction of a second before the computer went black.

No, those two tasks are not responsible for what you see. – Tino – 2014-03-22T08:30:42.020
