We are using AutoCAD 2012. While working on it frequently an error message appears and automatically the program get closed.

The errors msg is :

Welcome to the Autodesk Forums!

A place to start:

Though I suspect that the Error is random generated characters and that the KB articles will not directly solve your query.

Can you try to pinpoint what you are doing when the error's occur?

Hi,

>> The error commonly occur when i try to zoom or pan

Two ideas (currently) to that:

1) search for another driver for your graphicscard

2) turn off the hardware acceleration and see it the problem continues to occur. (command _3DCONFIG ==> Manual Tune)

That may not be the current one, search the www for an update of the driver.

BTW: what graphiccard do you use?

Hi,

In many cases, as already said, this fatal error, is related to a not updated driver for your graphic card, please try the following:

Install the last Video Card Driver checking them from the following websites:
http://usa.autodesk.com/adsk/servlet/syscert?id=18844534&siteID=123112
Video Card manufacturer (for example Nvidia - ATI etc.)
PC/Laptop manufacturer (for example HPDell etc.)

NVIDIA GeForce GTX 650. this is the graphic card we are using..

Hi,

>> Now one new error msg is coming

When does that error occur? Also when ZOOM or PAN is active? Or any other command or startup of AutoCAD, or same drawings, or loading same application, or ...?
