I woke my Yoga 710 up from sleep and after a minute or two it bluescreened with a message that was something to do with faulty hardware and a corrupted page. This is not the first time that this has happened, and the last couple of times it happened I ran various diagnostics including Memtest but found no fault. However this time I soon discovered that my wifi and Bluetooth weren't working. I rebooted, but this didn't fix it I looked in Device Manager and it says, with regard to the Bluetooth and wifi drivers, "Currently this hardware device is not connected to the computer".

Should I assume that my wifi/Bluetooth card is dead and order a replacement? Or is there something I can do to bring it back to life? Could opening the case, removing the adapter and then reseating it be worth a try? How can I test that it definitely is the wifi that is the problem and not something else?

EDIT:
The wifi and Bluetooth seem to have come back. I don't know if this is a coincidence, but that seemed to happen after I had rebooted my router. Just after I wrote the original part of this message the internet stopped working on my router (but the DSL connection was still active). I rebooted the router and waited until its internet connection was restored. Then I looked in Device Manager on the laptop and found that the wifi and Bluetooth drivers were no longer greyed out.
