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 bought dell XPS L502x with Intel centrino wireless N 1000 a year ago. I havn't had any problem with the wifi until the last 3 months. I get access to internet but it's slow and sometimes doesn't open websites. I have another computer that works perfectly with the same router.

I've recently bought a Dell Inspiron 660 running Windows 8 which has been working well. However, in the last week, it's been randomly switching to just a black screen and no keys / mouse etc have any effect. The only solution is to reboot, which works.
