Errors On Dbcc Checkdb

I've seen a lot of approaches to this, but I wanted to check here first before trying anything. Unfortunately, I just arrived and looking over the database, realized their backups have been failing for quite sometime. The application using the database is running fine so far, but backing it up freezes. I run DBCC CHECKDB (MyDB) WITH NO_INFOMSGS, ALL_ERRORMSGS and get:
