If this is a laptop it could be a bad battery other then that as other's have said if it was hardware related it won't display the shutting down message.
I would also check the scheduled task for possible things causing it. It could also be the user and not the computer.
I would sent a bit of time watching the user while it happens. And yea users are always too busy so in general I just document that fact they won't let look at the computer and let the user know until they give you the time you need to test it you cannot fix it.
This is a desktop computer, so not a battery issue. I checked the sleep settings and they are all turned off. Hibernation settings are also turned off. Something we noticed was that the computer is under her desk and the shutdown issue usually happened when she turned to get something from her printer. She admitted that her knee has accidentally hit the system and we're thinking that she may have brushed the power button.
I changed the button settings so the power button does nothing. Now I'll have to see if that is the problem. I assume you've checked Windows Updates to make sure it isn't trying to auto restart to complete the install of updates? If all that fails you can try disabling hardware to narrow done if a particular component or driver is the cause. Were recent updates installed? If so you can try rolling those back in case that corrupted something. Check your heat sink. That's not all in order, just a list of stuff to check.
The only times I've seen a clean shutdown due to hardware was from heat. The few times I've seen where it shutdown due to a different hardware issue, like a short in the motherboard or a problem with the battery component, the computer just turned off, no graceful shutdown. If the system did shut down for heat there should be a corresponding critical error in the event viewer. Thank you for your suggestions.
I really do appreciate you taking the time to respond. To answer a couple questions: we've rebooted the computer numerous times and the Windows updates are running ok. As computers require a specific amount of power to operate, too great a reduction can force the computer to shut down.
If this situation applies to your computer, unplug its power cord from the surge protector or battery back-up unit, and plug it directly into a wall outlet. Turn on the computer to see if the problem persists. If the computer stays powered on, the surge protector or battery back-up unit is bad and needs to be replaced.
An electrical short in a computer, which may cause power issues, happens when pieces of metal cause a path for electricity to flow through that shouldn't exist. Computers are full of screws, as they hold nearly every internal component in place, and from time to time, they can come loose.
Lift your computer and gently rotate it while gently shaking it from side to side. If you hear what sounds like small rocks banging around, you likely have loose screws inside the case.
Open the computer up and remove them. Verify the memory modules are properly seated in the memory slots on the motherboard. To do this, open the computer, remove the memory modules from their slots, and gently reseat them. It also is important to note that memory modules are installed in pairs, and sometimes in matching slots, which are designated by matching colors. Make sure the modules are firmly seated and the clamps on both sides of the modules snap into place. Plug in the power cord and turn the computer on to see if the issue is resolved.
The power supply voltage switch, a small red switch on the back of the power supply, may be on the wrong setting. If this switch's setting is not correct for your country, your computer may automatically power down.
