Hey I have such weird problem that I canít get solve it, I donít understand that what the hell is happening to my system. I am working on my desktop computer I have installed Microsoft Windows 7 ultimate operating system, I have Intel core 2 Duo @3.2GHz processor, has 2GB RAM, and 500GB hard drive. This type of error also cause when I open any of the window or explorer, it directly switch to the non-active mode, means nothing happen after doing this. The main problem is that when I select anything means any of the icons which is place on the desktop, system only select but not open that file of the folder. Weird thing is that task-bar is running nice; I can open from that side anything. I donít know why it is happening, if you have any information related to this situation. Please give it to me. Any suggestion would be greatly appreciated.
