Thanks for the well written problem description! - people could learn from this.
Now I have some things you can try, BF4 is a buggy game so it might not help but it's worth to try 🙂
- Try setting bf3.exe and Origin as a trusted application in the windows(/other) firewall
- Try testing if the problem is still there if you perform a clean boot ( http://support.microsoft.com/kb/929135 )
- If you have a Realtek soundcard try disabling it in the BIOS
- Make sure your CPU/other is not overheating, check if all fans are running and record and post your temperatures here
- Run Origin and Battlefield 4 as administrator ( http://technet.microsoft.com/en-us/magazine/ff431742.aspx )
Also, if you have video of the naked dancing part of your troubleshooting process that would be great!
