CAD tip # 7937:

AutoCAD freezes trying to Open a DWG drawing.

When AutoCAD freezes (hangs) in the "Open" dialog, there are usually two types of causes:

Collision with a system component taking care of file access, resp. attached to the Open dialog - e.g. a network redirector, antivirus software (e.g. a known problem with Norton 360 3.0), virtual disks, a thumbnail generator, etc. You can avoid displaying this dialog by temporary disabling of FILEDIA.
The Open dialog itself - if AutoCAD seemingly freezes instead of displaying this dialog, it is possible that the dialog is displayed "off-screen". Use the tip 5749 to take it back to the visible part of your screen.

Another reason is just a slow file access (apparent freezing) caused by a heavy load of your PC or network, or the source disk or a network resource is temporarily unavailable, or there is an error on the disk media.

Make sure you are using an AutoCAD version compatible with your operating system (e.g. not AutoCAD 2009 in Win7) and a certified graphics card driver.
