and what is the question for the support area ?
There are lots of hints in FAQ and within the forum if you get a CTD. What you tried already ? In special the cleanup of appdata, rolling-cache, old community-mods, if relevant the hosts file ( google-maps-replacement-mod ) , etc etc etc… sounds important after months of not playing.
If you ask for help, then for interesst is, as allways, the error-message from windows event log ( and new is: there is may be a CrashReport file within appdata ) and other informations you can give and which might important ( e.g. in-game settings, drivers, etc ).
