My computer restarts on its own after it's idle for a few minutes. Anyone know what's up?

Question

I have scanned with Norton. No good.

Answer 1

It sounds like you set the computer to shutdown after a period of inactivity. Right click any empty space on the desktop > Properties > click the "Screen Saver" tab > click [Power] > for "Turn off hard disk," choose Never. However, you can also choose to go in to either Standby or Hibernate mode after a period of inactivity. This is probably a better choice than shutting down the hard drive. Using the Standby mode, after a period of inactivity, the computer shutdowns most processes but there is a trickle of electricity keeping the CPU and motherboard alive. In Hibernate mode, the computer saves ever active process in to memory and then shuts down everything on the computer. In this mode, when you turn on the computer, the computer is exactly like you left it. As a general rule, Standby mode is recommended for desktop computers. Hibernate mode is recommended for laptops.
