Bluetooth problem

Hello,
I am new here. I am getting frustrated with my laptop. Its model is Hp compaq presario cq40-144tu with vista black installed. I am not able to transfer picture and audio file from my cellphone using my laptop's bluetooth and phone's bluetooth device. (also vice versa). i am trying to transfer file from my laptop to my cellphone, the bluetooth won't work. I tried almost everything that can be found in the Help and Support section of my laptop. But it seems that there's a problem with my bluetooth, whenever i try to configure it, it says that the discoverability and other settings cannot be saved. I also tried reinstalling bluetooth but it was unsuccessful, the program says that there are no bluetooth devices to be installed. I don't understand, I was able to use it before, why not now??? please help me.. Your help will be greatly appreciated..
