Get Error: Unhandled Access Violation Writing 0x3ed1f310 Exeption

[bbchung]

In past days, our desginer PC gets an error quit frequency in this week when using AutoCAD LT 2014.

"FATAL ERROR: Unhandled Access Violation Writing 0x3ed1f310 Exception at 3ed1f310h"

Search in Google, no any related error code.

Please help

The PC config:

Windows 7 Pro + SP1

Intel i5-4440, 8G RAM, Asus H81 chipset

Windows System Restore back to a month it alla worked and see if that helps. Otherwise start by identifying what has changed (plug something in or unplugged it perhaps?), added or deleted software, network changes, log in changes, peripheral changes, Windows settings changes etc.
