XPS2720 BSOD Errors

I have a new XPS 2720 AIO and I am getting BSOD Errors on an increasing frequency. Running Windows 8.1 64 bit. Tried to resolve using Dell System Detect but it will not finish installing as it says there is a version already installed. This is not the case.

I have had errors with:

KMODE_EXCEPTION_NOT HANDLED (NDIS.SYS)

DRIVER_IRQL_NOT_LESS_OR_EQUAL (BDFNDISF6.SYS)

and some others.

This is frustrating. Anyone can help here?
