Hello, I have small issue on mine operating system. Mine system was attacked by virus and after that when restart I get the blue screen death on every startup. So therefore I think to reinstall the windows 7 and to do this I have inserted mine windows 7 installation CD and while restarting system to install the windows 7, I got the error saying that” The application was unable to start correctly (0xc0000142)." And on this error dialog I have clicked the ok and after that i have logged on and after that I got the popup. The popup is to enter the password and domain which I don’t have. Now I don’t know how to solve this and so that I can install the windows 7, can anyone suggest on this.
