Case Sensitive Object Names?

My new DB seems to be "case-sensitive". I have a table named Bld_List.

Select * From Bld_List

returns all records in QA. However, if I don't follow the correct case

Select * From bld_list

I get this error: Invalid object name 'bld_list'.

Also, when I try to get rid of some unnecessary records by using this

DELETE
FROM Bld_List
WHERE (PRODUCT IN
(SELECT DISTINCT Product
FROM BldOff_Inv_Daily))

I get this error: Cannot resolve collation conflict for equal to operation.

I imagine I set something up wrong when I first built the DB, but I don't know what to look for.

Thanks
