frequent auto logoff in Windows 7

[Lysander]

I am having an Acer Aspire 4736 Laptop and using Windows 7 Ultimate. When I leave my laptop idle for approximately 2 minutes it automatically get log off. I attempt on the way to alter each and every one the settings in the advanced power settings. However at a standstill I am facing the trouble. It turn out to be irritating to log in all time, at whatever time it gets logged off
As well, in Personalization, at what time I attempt on the way to place the Theme to Aero Theme - Windows 7, it get changed back to Unsaved Theme. I have already scanned my computer with anti-virus and did not find any thing.
Does anybody have a answer for this?Regards,
