My computer has an irritating behavior lately. It refreshes every 5 seconds. This is visible because you can see that an application window is flickering and when you select from a combo box, the drop down returns back when refresh is triggered again. I tried closing all open applications to trace what may have caused the refreshing cycle but found that it didn't came from the applications. Stopping windows services one by one is not a good idea. Is there a way to trace which application/service/background process is invoking the refresh?
