My windows operating system is not working properly. It's taking too much time to start. Sometime, after starting, internet connection isn't being connected. After restarting PC it connectes. Sometimes, after starting PC, a message shows that the windows wasn't shut down properly. Then some options come i.e. "Start windows normally" and so on. After pressing 'Enter' it starts.
So, please help me.
N.B. I use Windows-7as Operating System, Mozilla Firefox as browser and
