I recently downloaded AutoCAD 2012 for students on my custom built PC. My technical specs are as follows: Windows 7 Professional 64 bit. Gigabyte X58A UD7 with f4 BIOS. My processor is an intel quad-core i7 920 running at 2.66 gigahertz. I have four gigabytes of memory and a hard disc with over 350 gigabytes of space left.I downloaded and installed the program without incident, but when I started it up to design an architectural concept, the program announced that the Heidi driver had stopped functioning, and that it was switching to the core driver. Ten seconds later, AutoCAD froze and within seconds my computer developed the blue screen and promptly rebooted. After rebooting, I logged in and started the program again. This time, the program froze immediately. After numerous reboots, I decided to troubleshoot the program for compatibility, and Windows reported that the program ACAD was incompatible.
Please help me to resolve this problem.
If you can get AutoCAD to stay open for a minute, try typing 3DCONFIG in the command line and hit the enter key. When the dialog opens, click the "Manual Tune" button, and uncheck "Enable hardware acceleration". Click Ok to exit the dialog boxes.
What type of graphics card do you have installed? and where did you download the updated driver from?
You may have inadequate video card for ACAD 2012, so I would suggest checking your video card against Autodesk Certified Graphics Hardware list.
You can also try turning off hardware acceleration as follows:
1. Right-click the AutoCAD icon on your desktop > Properties
2. By default the Target is: "C:\Program Files\Autodesk\AutoCAD 2012 - English\acad.exe"
3. Add a space and then /nohardware at the end, so the new Target would be:
" "C:\Program Files\Autodesk\AutoCAD 2012 - English\acad.exe" /nohardware
4. Apply > OK > Re-launch AutoCAD
