Everquest - Instanced zones and crashFollow

Morning all,

Every time I go to an instanced zone (LDON, MM, GoD, etc...) my computer goes link dead and eventually a black screen comes up with the words "You have been disconnected." The disconnect part is incorrect. It boots me back to the character screen.

I have completed a file scan and results still the same. It just happens in an instance zone. Very annoying!

Please advise.

I have all the expansions.
