Hello,Thank you for posting on Microsoft Forum.I understand that you are facing issues with Bluetooth device on one of your Windows 7 computer.The yellow exclamation mark you have mentioned is when the drivers are not installed. You need to download the drivers for that specific device. As you have already tried to install the drivers from the DVD, I would suggest you to download appropriatedrivers from the Manufacturer’s website and then you can try to install them.Also you may try to install all the latest windows updates and see if it helps.For further reference you may refer to the following articles.andI hope this information helps.
