Spark closes 3 seconds after opening

I have a weird thing happen a week ago. We are using Spark and for one user his spark will close when he is barely going to log in. I have tried uninstalling, delete all spark files and folders, spark keys, then do an install but still the same thing. I have also logged in as another user to the machine and tried to log in but the same issue occurs on this laptop. Everyone elses spark works just fine on their laptops Any Ideas on what might be causing spark to close???
