OK I FIXED THIS. DO THE FOLLOWING.
1.right click C: Drive in MY COMPUTER, click properties, tools, then Error checking, check now, u may need to restart windows for it to do the scan,
2. repair game with all usb sockets unplugged apart from kboard/mouse, i noticed when replairing bf4 my mic disabled so it was doing somthing with the drivers.
3rd thing i did was Download and replace the following DLL files, Some we actually missing, not sure why.
