All I can suggest is to uninstall the Bluetooth driver, reboot the PC and then try installing it again. Make sure you use the latest available driver version. Since the Download Center is not working this weekend, you'll have to wait until tomorrow to ascertain if you have the latest.
If this doesn't work, you likely have a hardware failure and will have to have the NUC replaced. In this case, contact Intel Customer Support to arrange an RMA...
Hope this helps,
Thanks for the response. I have narrowed the problem to down to happening when I install Windows 8.1 on a USB flash drive and boot from flash drive. Only the Bluetooth driver has a yellow bang, all other drivers are fine.
I don't see the issue when I install Windows on M.2 SATA SSD on the NUC.
Why would the Bluetooth driver not load properly from flash drive?

animan, have you tried installing the driver in safe mode?
Try downloading the file one more time and if possible save it on a different flash drive.
One more thing, you can try is uninstalling the driver with the following method;
- Open the Device Manager.
- Expand the Display Bluetooth section.
- Find the Intel(R) Wireless Bluetooth Driver.
- Right click Intel(R) Wireless Bluetooth and select Uninstall.
- Select the check box Delete the driver software for this device.
- Reboot the computer after uninstall process has finished.
