I recently upgraded my processor from an (1.6ghz) E1200 Celeron to a (2.2ghz) E1500 Celeron. I have an ECS Motherboard 945GCT Intel motherboard. My problem is that it won't let us play some of our older games anymore. This computer is not hooked up to the internet so I know it is not from an update. One game it does not allow us to play is Star Wars Jedi Knight 2. Everytime we try to launch it it gets shut down by Vista saying that D.E.P. has shut it down. I went into D.E.P. and put it on the list to not shut down and it continues to do it. How do I fix this and what is wrong??
