Hi guys I got Battlefield 3 the other day and installed punkbuster in order to play online and have had problems with my computer since. Is it possible that punkbuster is causing the problems.
Possibility. Punkbuster is crap, could always try and reinstall it.
+1 Punkbuster has always been trash and has caused funny issues before especially back in the days of the first CoD and Battlefield 1942
