Bluetooth Software For Vista My Computer Can't Detect Bluetooth After Upgrading From Vista To 7.?

My computer can't detect bluetooth after upgrading from Vista to 7.? - bluetooth software for vista

I have a laptop Asus G51VX. It has integrated Bluetooth, and was there when I've seen. But now I'm really trying to use and has disappeared. I tried to download various Bluetooth software, but each of them say they can not recognize the Bluetooth device. I tried, one on the Asus site, but it always says it does not detect Bluetooth. Is there a way to solve this problem?
