When you launch AutoCAD you see that the Start page is truncated or skewed.
I've had several calls on this now and they also typically mention that the monitor flashes black during some commands too. This typically indicates a graphics/video card/driver type of problem.
We have resolved it successfully by changing a Windows setting.
- Right click on your desktop and select "Personalize"
- In the lower left corner select "Display"
- Select "Smaller"
- Click "OK"
- Reboot the computer.
You should be fine now.
