WP nonresponsive?

Has anyone been having problems with WP x7 becoming nonresponsive after working for awhile and then leaving the computer for a short time?  Trying to determine if this is a computer issue or a WP issue..  I have a Dell computer which is now almost a year old but it has been having issues since day one... no luck finding the problem.  With ONLY WP open it is doing this and IT is saying it is likely a problem with software - namely WP - and not the computer itself.   Looking for suggestions....

  • Under the Windows Control Panel, you might check yout the settings made for PowerOptions to see if something there might be causing the problem. Some computers seem to have problems when set to go into sleep mode, problems when you wake them up.
