Is there any way I can put a timer on my computer to shut down (windows 7)?

-I am streaming movies from my pc to my ps3 and would like the pc to turn off in around 3 hours, is there any way it will automatically shut down. thankyou.Control Panel -> Power Options -> Edit Plan SettingsYou're running Windows 7 (the same as I am), so your menus are different from past Window versions.



Start Menu --> Control Panel --> System and Security --> Power Options. On the far left menu, you'll see "Change when the computer sleeps." You can not, unfortunately, tell the computer to turn off completely. You can tell it to go into a standby sleep mode after x hours or x minutes. Likewise, you can tell it to turn the display screen off after x hours or x minutes, as well.

some bios support a start up and shut down time.... and there maybe programs just google some
sorry you will need to get a professional to sort out that situation
