Hi I have recently configured an desktop PC and it has all the latest configuration. I have installed the windows 7 operating system and Intel core i3 processor. But from yesterday i have started facing an unusual problem and that is whenever i click on the icons of the system programs then they are not responding. The thing here is that any of the icon on my desktop is so not working properly. I have recently installed the windows 7 and earlier i was using the windows XP and during that period of time i have never received any such problem. Please help me to solve this problem and also let me know how to did it occur. Does anybody ever had face such kind problem if yes than how did you people got rid of it.
