Sometimes when I am in the game it just exits and the desktop comes up...sometimes the resolution is changed to what the game was and sometimes not. Anyways it's really annoying, and it would suck to have happen at a crucial moment. Does any one have a fix?

P.S. I don't have EZDesk at all or enabled.

Such behavor is often triggered by some kind of sound-card problem.
You might want to check that you have the latest drivers.
Another thing you can do is to minimize the number of programs running.
Go to the Start menu select Run and type Msconfig.Select Start and
uncheck all boxes.Then restart your machine.No programs at all will
be running in the background now.
Hope some of this is useful.Good luck'n happy gaming
