I am using the HP Pavilion Dv6 notebook. It came with Windows 7. It is not new I bought this second hand. I had formatted the pc and installed Windows 7 back on that. The installation was fine. After that there were some new updates. This were also automatically installed. When everything was done upon reboot the system just freeze. It is very slow and takes long time to start. Sometime it stuck on the welcome screen for long time. I need a bit help to fix the issue.
