In our production environment, we are seeing frequest deadlocks due to locks on the resources. I have attached DeadlockGraphs captured for the same. Need your help on finding the fix to solve the problem.
Thanks in advance.

can you tell me size of tableA and execution time for the below query?
SELECT * from FROM tableA
UPDATE A SET A.IsError=1 FROM Table1 A LEFT JOIN Table2 B ON B.Id=A.Id LEFT JOIN Table3 C ON C.Id = A.Id WHERE (C.Id IS NOT NULL OR B.Id IS NOT NULL) UPDATE A SET A.IsError=1 FROM Table1 A LEFT JOIN Table2 B ON B.Id = A.Id LEFT JOIN Table3 C ON C.Id = A.Id WHERE (C.Id IS NOT NULL OR B.Id IS NOT NULL)
Thanigaivel.

Below is the size of the tableA
name rows reserved data index_size unused
TableA 49132 19352 KB 8464 KB 10280 KB 608 KB
Select * from tableA - took 00:00:01
Update query - took 00:00:01
Adding additional indexes will fix the issue? or providing locking hint in the queries will be the best option to fix it?

Either we can use lock hint based on sensitive of data or Non Clustered Index which will create addition maintenance work. My choice is Non Clustered index.
