SSMS is not listing table and views objects though the objects are listed when I execute TSql string "SELECT * FROM sys.Tables"

Question

I have a db, call it xyz.mdb
It suddenly is that SSMS is not listing the table objects nor the Views.  SELECT * FROM sys.Tables and SELECT * FROM sys.Views work very fine.  But when I click on the tables node, on Objects Explorer, Only the Systems Tables and File Tables folders
show. 
Other DBs on same SQL instance do not show same problem.  They are all working very fine.
I have backed up and restored this db on other computers and the behaviour is the same.  Incidentally right-clicking the db and clicking Properties throws up this error message.
-------------------------------------------------------------------------Error!
Cannot show requested dialog.
Property Size is not available for Database '[Pliny E DB - NOA 2014]'. This property may not exist for this object, or may not be retrievable due to insufficient access rights.  (Microsoft.SqlServer.Smo)

When I try to Refrresh the Tables node on Object Explorer, I get this other:
------------------------------Error!
SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x9090d9b7; actual: 0x909001b4). It occurred during a read of page (1:1173) in database ID 21 at offset 0x0000000092a000 in file 'c:\Databases\Clients\NOA\Pliny E DB -
NOA 2014.mdf'.  Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check
(DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online. (Microsoft SQL Server, Error: 824)

The Help link of course is not valid any more.

Your database is corrupted and you need to run.
DBCC CHECKDB
You already have a backup so do it...
