Hi friends, I just installed windows 7 on to my system. It was being working fine for two weeks after installation. But now when I start my computer it get hang for about two to three minutes after I start. The mouse work for sometime but it also get stop moving. Any applications working behind such as music also create some crazy type of sound while it get freeze. Keyboard also gets stop operating. This was not the problem with my previous operating system. It worked fine. What can be the reason for it.
