Inspiron one 2330 freezes at grey screen after Windows 10 upgrade

A couple of days ago I upgraded to Windows 10.  There were no issues or errors with upgrade. Everything went smoothly and everything worked for a couple of days.  I powered the PC off and on a number of times over two or three days.  Today when I turned on the PC it began the boot up process the Dell logo appears then the Windows logo displays briefly then the computer freezes on a grey screen.  

Is this a driver issue?   How can I resolve this issue?
