Was it working okay before some point in time? If so, what changed just before it started doing this?

A different data set?
New hardware installed?
Windows updates?
New drivers?

For starters....

Make sure you have a supported video card, and a recommended/certified driver for it. (See http://usa.autodesk.com/adsk/servlet/syscert?id=18844534&siteID=123112 )

Make sure your %temp% folder is not bloated - clean it out.

Hi @vaibhav.deshmukh, 

A few tests to run so that we can narrow down where the issue might be: 

• Test AutoCAD LT in a new user login with full admin rights. This way we can test AutoCAD LT in a default settings environment. 
• Is this happening with all of your files? Test a brand new file and capture of a screengrab should a fatal error message show up. 

A few questions; 

• Do you have other versions of AutoCAD LT on your system? 2017,2016,2015? 
• What OS are you running? 

[vaibhav.deshmukh]

Hello,

1. I have other version of Autocad also like 2011, 2013, 2015

2. I have all the system running Windows 7 Pro and in one system Win 10 Pro

Thanks for providing that information.  

Are you running into this issue with other releases? Have you applied all updates? 

If possible could you provide the answers to the rest of my questions? It helps give me and others a better idea of what suggestions to offer up next. 

Thanks.

To add for any other user who might have a similar issue. 

You can also find the information below at this article link: 

There are several ways to troubleshoot the problem:

• Update AutoCAD.
  Updates for latest releases are acquired via the Autodesk Desktop App. Right-click its icon down on the status bar next to the time and pick "Check now." You may also download updates through your Autodesk Account (see How to Access Product Updates in Autodesk Accounts). For older products, see Autodesk Downloads.

• Try opening another drawing.
  If you can open another drawing, the original drawing may be corrupt and require repair.
  See: How to repair corrupt AutoCAD files

• Uninstall any antivirus or desktop locking programs.
  These programs can cause errors in AutoCAD, since they prevent the system environment from working. 

• Reset AutoCAD to defaults.
  See: How to reset AutoCAD to defaults

• Turn off Hardware Acceleration.
  See: Starting AutoCAD-based products without hardware video acceleration

• Update your graphics driver.
  Install the latest graphics driver from your video card manufacturer or use an AutoCAD-certified driver.
  See: How to update your system to the latest certified video driver

• Try logging in under a new Administrator Windows Account.
  If you create a new account and can successfully open the drawing, you can either use that account or rebuild the user profile in Windows.
  See: How to create a new local administrator Windows user account

• If DisplayLink Core software is installed on your system, try uninstalling it.
• Do a full uninstall and reinstall of AutoCAD.
  See:  Remove All Products from a Windows System

• Uninstall and reinstall the .NET Framework.
  See: How to remove and reinstall the Microsoft .NET Framework

• Uninstall and reinstall Visual C++.
  See: How to remove and reinstall Microsoft Visual C++ Runtime Libraries

• Clear the digital signature icons and then uninstall and reinstall the application.
