Major FPS Drop after half time

Since i bought the game on special there has been two patches, neither of them fixed my issue. I have updated all my drivers and followed countless guides, i have to restart my PC after every match. Not only is there massive frame drops, my game freezes during the frame drops and the commentary becomes distorted. The music in the menu also starts distorting after one game. This is not a hardware issue, i can run much more intense games. I am hoping someone from EA or the community can help me, im not hopeful as i am not the only one with this issue.
