I have a laptop having windows 7 installed.It has a RAM of capacity 4GB. Everything was working fine but from last couple of days, it hangs too much and becomes unresponsive most of the times. I am unable to move my mouse cursor. After checking the processes list, I came to know that "svchost.exe" is consuming most of the RAM and is the only cause for hang and unresponsive screen.Is there any way to stop it from working? If yes then how? Please reply as soon as possible.
