Re: Green rectangles appear, system is immediately unresponsive and then reboots
No idea what could be causing that.
The first place to look would be the logs though.
I suspect it's the only way to get a handle on what is happening.
When the system freezes can you get to a console (ALT + F1) and restart lightdm ?
Does the magic key combination reboot gracefully ?
sudo service lightdm restart
alt + sysReq (keep depressed then hit the next 6 keys, one after another, with a 3 second gap between) r e i s u b
I.E. Is it X or the kernel hanging ?
Zip then up and add them as attachments in your next post.
Obviously make sure you get the correct version of the logs. i.e. get the xorg log file for when the system was actually playing up.
As for the BIOS screen, start tapping the BIOS key before starting the PC and hammer it hard
