Inspiron 1520 Bios - Help Please!

Hi there,i hope someone can help me with my problem that i made in BIOS settings of my Inspiron 1520 (sorry if my english isn't good :smileyhappy: ) Mistakenly i loaded default settings in my laptop BIOS (before i reinstalling the windows vista os ) and now after install of the system i can't use bluetooth and wi-fi device (also on the right side of my laptop there is no blue light for these two devices,and they are not listed in device manager). After installation of vista os i also installed all drivers that came on reinstall CDs with my laptop but bluetooth and wi-fi don't work,so i tried to download drivers from dell support page and install them manualy but that didn't help either. Only thing that i did is to load default settings in BIOS,but it seems that those settings are not the same as the settings that were in BIOS when i buy my laptop and now i dont know how to put the original settings back. I also realized that windows vista experience index isn't same after mading these changes in BIOS and reinstalling the system (before my score was 4,7 and now the score is 2,8 and score for graphic is now beter then before,but score for CPU and memory is lower then before) When i enter in BIOS settings bluetooth device and wi-fi are enabled and all fields are on the default factory settings but something is definitely wrong. Is there any way that someones help me with these? Please?

 

When i try to install driver for bluetooth (downloaded from dell website) i got this message : Activate bluetooth using Fn+F2 or radio On/Off switch ??

 

Here is the solution if anyone have similiar problem ,it also can be used on other Inspiron and Vostro models. Just run this application and when the bluetooth icon apears in taskbar install bluetooth driver and enyoy
