Bluetooth driver/network card fail

Hello, 

Started up a game on my PC which crashed then had a windows blue screen error. On restarting I still have functioning WiFi but no Bluetooth icon in the bottom right toolbar system shortcut. 

I restarted as a first attempt to fix but this didn't work so I followed windows online troubleshooting steps (Bluetooth troubleshooter-->Not detected-->Checked drivers-->No drivers-->Installed Drivers-->Still not appearing in Device manager).

Then went into My Dell Support App-->Hardware Troubleshooting to test the network card and the test just said failed (no info about what in particular failed). Skeptical it is a problem with the hardware as the WiFi is still working fine. 

Retried installing all the drivers on Dells site relating to the network card and an that caused a new problem of the Killer WiFi app not opening (although WiFi is still fine). 

Any help would be greatly appreciated. 

Thanks,

Will
