Dell Inspiron N5110 Bluetooth Problems

Questions:
I have recently purchased a Dell Inspiron 15r n5110 (approx 3 weeks ago)( dell inspiron n5110 battery). but i can not use the bluetooth. I downloaded the driver from Dell ( i'm sure the driver is correct because i downloaded using my service tag ) , but whenever i try to install , it say "Activate bluetooth using wireless switch" althought i have already turn the wireless on ( Fn + F2).
I tried to let windows install the driver it self but there is always an error called Code 43 : Windows has stopped this device because it has reported problems.
After i uninstall the driver, on the device manager the bluetooth device is shown as unknow device.
So i use a software called : Driver Identifier and download a software call BlueSoleil , after installing this, everything seemed to be fine.
But it is just for look , nothing changed , i can not start the bluetooth device, and in the control panel it does not recognize any bluetooth device.
My device hardware ids is : USB\VID_0CF3&PID_3002&REV_0001 USB\VID_0CF3&PID_3002 Answers:
I purchased my Dell Inspiron Core i5 N5110 ( dell inspiron n5110 battery, dell laptop battery n5010, dell 15r batteries) a week ago. If once you get done installing your driver by choosing the wrong one, or not in proper order, you will have to reinstall your operating system because the Bluetooth driver once installed will not be uninstalled properly if you selected and installed the wrong driver. I installed my OS thrice then I came to know how should I install the OS and Drivers to make this machine 100% functional.
It might not be beneficial for someone but might be a complete solution for anyone, just try, my Wireless Driver problem, Bluetooth problem, PCI Simple Communication Controller error and mic problem were resolved by following the order of installation. There are almost approx 15 drivers that needs a restart of your machine, either asked or not, you should restart every time.
(All this is for Windows 7 x64 - Go to the Dell website and follow the order of the headings and the numbered order of the drivers - The procedure WORKED 100% FOR ME, there is no guarantee for the others)
