Program not responding

This is the Windows' way of telling the User that is or might having a problem. Many computer Users when encounters the phrase " program is not responding" they don't understand it in return they end up doing what they not suppose to do. Operating System, software program and drivers might stop respoding or sometimes cause other programs to to stop responding.

Causes to this may be any of the followings

1 Conflict of software or hardware resources between two programs.
2 Lack of systems' resources..
3 Programming Errors
4 Scattered data in the hard disk.
5 Software design Error
6 Viruses and spywares

Solutions
You can kill the particular program not responding via task manager( press CTRL+SHIFT+ESC). You do this if you can not wait, sometimes other programs take time to respond to the Users request due to CPU intensive calculations which when complited, program may start responding again. As viruses may cause this, therefore you need to make sure that the anti-virus is running and up to date. Make sure that Windows and hardware drivers are up to date.

In most cases this may be a minor issue yet sometime it lead to the deeper issue.
