Give this a try turn off PC then un-plug modem for 15 min. Then plug it back in and let it fully boot up and then turn on your PC and test. Also do all this for settings please and some of this you have done.....

If all this fails to fix it then try this...
C:\Users\your PC Name\Documents\Battlefield 3
BF3 folder in my documents holds game configs and screen shots even if BF3 is installed on different drive. When you uninstall BF3 it does NOT remove this folder. So when you install the game again you can still have the same issues. Even if its not a new install it is still worth trying as the game cfg could be mucked up.
1- Go to my Documents and remove BF3 folder place it on your Desktop.
2- Be warned you do have to set up your in game settings again.
3-Repair BF3
4- When done go test your game. If it fails reboot your PC and run repair game again and test BF3.
