Just a guess… are you using a Razer mouse and/or keyboard ?
If so, check this topic:

If you are not using a Razer mouse/keyboard, then you should provide your DxDiag report; see Obtaining System Files - Blizzard Support for the procedures on how to create it.

Once you have created the report, post it in your reply between two lines of 3 tildes, as in:
