Computer Goes Into Standby By Itself

[PC_User]

After 10 minutes of idle time, my computer goes into standby mode by itself.

How can I disable this and stop it from happening? In power options, I have it set to home desktop and everything is set to 'never.' This just started happening randomly...

Go back and set them to a certain time. Restart. Then go in and see if those changes held. If so, change them back to never, restart, and see if those changes held again. If so, then wait 10min and see if they truly held.
