I just had my samsung 320Gb hard disk sata disk which went dead on me and have now lost all my data. I have now installed a new drive and tried to restore my OS to original factory settings with my disks which I created around two years ago.

I click START >Shutdown and have to wait and wait forever (3-5minutes) for the final prompt to either restart/shutdown/log off.Its is real annoying. I am using a 2007(bios) Latitude Dell 520 laptop (purchased second hand).

After facing issues with my laptop, I have done re installed windows 7. All seems to be ok, but I can't access WiFi. Nothing at all shows up in Network and Sharing Center, the only options I get is to connect using an cable. There are no WiFi options at all.
