Chain hitting Chainring on 105

[DSAINT34]

Can anyone help i am going mad, my chain is hitting my chainring in the lower 10 gears but only 11-15...
I have adjusted the d and tightened the cable but cannot seem to get it not hit the chain ring in those gears....
Any advice would be welcome as I am new to cycling and getting frustrated....
many thanks

We really need a clearer description to offer advice<br />
What is the chain hitting, in what gear combinations, what if anything has changed on the bike recently, what does "in the lower 10 gears but only 11-15" mean?
