is my nvidia 880 dead ?

Well just finished my last exam at uni and decided to load up origin for a bash of bf4 and noticed my NVidia gtx880 is not showing. so I pressed ctrl + f5 to switch graphics and still it wasn't showing...
corrupted driver maybe ? ok so I uninstalled the driver and downloaded the latest from NVidia site and when I try and install the driver says no compatible hardware detected or words to that effect.
ok this has happened before maybe im running soley on the intel gpu.. so I pressed ctrl + f5...

is my nvidia 880 dead ?
