Re: [PC]Battlefield 3 Stuck at Connecting (Black "Loading" Screen)

If the clean boot did not change anything then it is not a program so  no need to remove them.

When you reinstalled BF3 did you remove the BF3 folder in my documents? If no try this...

Don't give up we just have to find the correct fix for you and sadly it does not always come fast.

Try this please.... 

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 or trash.
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.
