I just built a new machine, see my signature for specs. However, I am experiencing the same thing with COD4 taking a long time to load. I don't have Any anti-virus software running. When you look in task manager, it states its not responding. Now, before this, I had an XP machine running on the same network and everything worked just fine. Game would load in 3-5 seconds. Now, on my new rig, running Vista Ultimate 64 bit, it takes forever to launch. BF2, all the half life games load pretty quickly compaired to COD4. Anyone have a solution yet?
