Clean boot in Windows Vista/7:
I would suggest that you try running your system using the Windows clean boot option. That way you would be able to locate any program that might be interfering with the game. 
The instructions for clean booting your operating system can be found at the below link: -
http://support.microsoft.com/kb/929135

Affinity:
· Customer needs to login to Origin (If it is a digital download) 
· Run the task manager  (Ctrl-alt-delete) 
· Go to the "Process tab" in task manager 
· Right click on Origin.exe 
· You will get the option of "set affinity", click on it 
· You wil get CPU 0, CPU 1, CPU 2 and CPU 3 options. 
· You need to select CPU 1. 
· Click on "Apply" and then "OK" 
After this please launch the game from Origin. 
Then you will be automatically redirected to Battlelog.
Click on "Multiplayer" on Battlelog
Browse all servers
Select any one server
You should be able to join the server. After joining the server select "Alt+ Enter" to run the game in full screen mode

Disable firewall and antivirus:

I would suggest that you try temporarily disabling any firewalls you have running on your system: - • Software firewalls can simply be turned off, usually by right clicking on the icons 
near your clock and selecting "Close" or "Exit". • Hardware firewalls should be bypassed by going from the computer directly to your modem, skipping any router you may have.
Open Windows Firewall by clicking the Start button , clicking Control Panel, clicking Security, and then clicking Windows Firewall.
Click Turn Windows Firewall on or off.   If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Click Off (not recommended), and then click OK.

Allow a program to communicate through Windows Firewall
1. Open Windows Firewall by clicking the Start button 
, clicking Control Panel, clicking Security, and then clicking Windows Firewall.
2. In the left pane, click Allow a program through Windows Firewall. 
 If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Select the check box next to the program you want to allow, and then click OK.
