Cant turn wireless capabilities because the Hardware switch is turned off

I have a Dell Inspiron 15r 5537. I have it for around 8-9 months or so. Everything was fine with it until yesterday when suddenly neither the WiFi nor the ethernet would connect to the network. This is what i did to overcome the issue:
- Troubleshoot the problem, the result was " Wireless capability is turned off - Not Fixed ".
- Checked Intel PROSet Wireless connection utility and tried to enable Wifi, and the result was Hardware Switch is OFF.
- The switch (via Fn + F2) is already on and always was.
- Since i had a presentation coming up soon, i used System restore suspecting it as a windows update that messed things up, and it still didnt work.

-Checked for hardware problems and the result was the Network card is healthy.

- Disabled/Enabled from Device Manager.
- Clean formatted Windows 7. I have original Windows 7 and 8 with keys, fully activated and installed both of them one by one.

The problem still persists. What do i do? 

My drivers are fully updated, the OS is fully activated, every new driver provided by both Dell and Intel have been installed. As you can see i have left no stone unturned. What do i do from now? Thanks.
