You are not talking very polite and not to EA, this is a community driven support forum which means it's normal people like you in here, so try to behave 😉
Also: PunkBuster is not an EA-made program. It is developed by Even Balance and used in many online games.
Now the first thing you should do is download the installer software from: http://www.evenbalance.com/downloads/pbsvc/pbsvc.exe then reinstall Punkbuster and notice if any error pop up when it runs its selftest, you can also run the test without reinstalling. Copy past the results in here.
Secondly, if you run some type of personal firewall or security software, make sure that you configure it to fully allow Punkbuster, especially PnkBstrA.exe. Remember there's a windows firewall also, allow it there as well. Also, if you run Windows 7, which you didn't mention, then users have reported that the following steps corrected issues for them: 1) login as an Administrator user, 2) open Windows Explorer and browse to c:\windows\system32 (or wherever the windows folder is on your machine) - note: if you run Windows 7 64 bit, you need to browse to c:\windows\syswow64 instead, 3) scroll down and find PnkBstrA.exe, 4) right-click PnkBstrA.exe and choose Properties, 5) click the Compatiblity tab, 6) click the button at the bottom of the window that reads "Change settings for all users", 7) click the checkbox for "Run this program as an administrator", 8) click the "Ok" buttons to accept the changes and get back out.
If the above doesn't work, try closing all firewalls, antivirus, antimalware, security programs and see if that helps.
Also turn off VPN's and other programs that can affect your network in nongaming kinda ways.
Lastly, if the above does not work then a format probably will solve whatever your problem is, or you can play on servers without Punkbuster which might not be that fun ☹️
