You are running on Windows 7 x64 and you are running AutoCAD 2012. AutoCAD was running previously and when you launch it now, you get the Windows Blue Screen of Death.
You have tried the following:
In this case....it was not Autocad, it was a Trojan called the Google Redirect Virus. Quite a little nasty bug to find and get rid of. It attaches itself to a running process so it doesn’t get picked up by the Anti-Virus programs. In this case, it must have attached to an acad.exe process and when we tried run AutoCAD, it caused the crash. I downloaded TDSSKiller from Kaspersky and was able to find it and remove and everything is working fine now.
