I USSUALLY GOT THE FATAL ERROR MESSAGES AFTER CLOSING THE CAD FILES:
AUTOCAD ERROR ABORTING
"FATAL ERROR:
UNHANDLED ACCESS VIOLATION READING
0x43ae2380 Exception at 33ed3feah"
 
OR:
"FATAL ERROR:
UNHANDLE ACCESS VIOLATION READING
0x41d91c3f Exception at 6543ff9h"
 
PLEASE ADVISE

 What happen when you use save as option? This happen every drawing?

What version of Autocad are you running?Do you have all service packs installed?Have you tried running a Repair?What operating system are you running?Does your computer meet the minimum system requirements for your version of Autocad?What are your computer specs?

It didn't happen with save as option.
It happenned mostly with drawings with hatch paterns (I guess).
 
Such drawings, after i opened, i uassualyy got the following texts at the command:
DO YOU REALLY WANT TO DO THIS? <N>
 
I hit ENTER, then got the message:
 
EVERYTHING HAS BEEN UNDONE
YES or NO PLEASE?
 
I have to hit ENTER or Esc several times until i get the COMMAND: back
 
After working through with the drawing, i saved first then when i close the drawing, i got the FATAL ERROR (Sometime NOT).
 
Thank you very much for your advises...
