Recently in SharePoint server I got an error when trying to do almost any action.
The error was Exception from HRESULT: 0x80040E14.
After sometime I did find out, that my C drive has gone out of disk space, and that caused SQL transaction log creation failure which resulted this error.
So freeing up more space on C drive solved my problem.
You will be able to get more details of the error by checking SharePoint log files.
