How can I stop my PC from booting?

Occasionally, like once/week or less often, I shutdown this x64W7 SP1 desktop. Looking at the schedule tasks that ran last night (after shutdown) there are a number of potential culprits. Is there some command line entry I could make to override wake or can I disable something in my ASUS motherboard to prevent this? Thank you!

 

You shut it down - or it shut itself down?

I shut it down. I'll take a screenshot of the suspects and edit this post.

Could be a few other possibilities too. Thank you!

 

Don't power it up

Seriously though, i hope you get it sorted

 

I just went through dozens of scheduled task and there is not one that has "Wake computer to run this task" enabled.

 

Are you sure it's shut down? I don't think I've seen anything on Windows that can cold boot a system, unless you mean waking from sleep mode.

 

You could check you BIOS settings to see if there is an auto start enabled. When I bought my Dell OptiPlex every day at 5:30 am the system would start on its own. I checked my scheduled tasks, also disabled the Nic card start feature. And still it keep auto starting. Finally I went into BIOS and there it was.

 

I still don't understand what you're trying to accomplish.
Wake from sleep/hibernation/shutdown mode?
Shutdown machine?
Prevent shutdown?

I assumed that if the question had the word "boot" in it that most folks would realize that the PC has been shutdown but starts by itself. If I had merely used the word "wake" I could understand the confusion. I've never read describing wake from sleep or hibernation as booting. Actually, I did disable some features in the BIOS that could have allowed booting and last night it stayed off. The odd thing is they were previously disabled.

 

I think I get it now.
Some NICs have wake-on-lan feature.
There are many options really.

You can't boot up a system through task scheduler. If the system is down, then the task scheduler can't run. This only works if the system is in standby (which isn't a boot up heh).

"Some features" like alarms in "power" section of the BIOS, right?
