I'm having similar issues. The PC in question has Geforce 6100 onboard graphics. It was previously running Ubuntu 14.04 without any issues.
I then upgraded the install to 16.04.
With nouveau, the system doesn't run stable. As soon as there is a little bit of load, I get diagonal stripes on the monitor (see http://i.imgur.com/X3Am8U2.jpg) and it appears to lock up (can't switch to text console either).
I tried a fresh install of 16.04, switching from i686 to amd-x64 in the process.
The lockups with the diagonal stripes remain.
So I tried nvidia-304 instead. Lots of problems there. First I get X11 with just the desktop and no menus and launchers.
Then I got black screen with just the mouse pointer.
Currently, I get a desktop but with massive screen corruption. I am also getting the errors that were reported in comment #2.
