Dude, go to the Punkbuster site and get the updater. Once youve installed it onto your comp, open it and add all the games in the list then click update, it may take a while.

Try BF2142 again should be ok, maybe punkbuster files need updating, also when playing well actually before you start playing open task manager and end task all your unwanted processes.

Try to keep processes under 40 while gaming, you will notice games become more responsive and fluid gameplay, try what ive suggested and let us know how you get on.
