The problem may just be that the Bluetooth driver is not working properly. Here is how you can test it. Go to Windows + C to get to the charms bar. Then go to settings and click on PC info. After that, click on Device Manager and look at the Bluetooth symbol. If there is some sort of exclamation point or foreign symbol, then this is probably the issue. The best thing to do after this is to download the driver again and re-install. If you need help, check on this link if help is needed.
