Had the same problem, I fixed it.

1. Open SQL Server Configuration manager
2. Click on the SQL Server Services (on the left)
3. Double-click on the SQL Server Instance that I wanted to start
4. Select the Built-in account radio button in the Log On tab and choose Local system from the dropdown menu
5. Click apply at the bottom, then right click the instance and select Start
