I'm not sure what is causing the reboot problem, but it appears that the system is not loading the correct graphics driver for your Intel card.  Let's see if we can force it to load correct driver and see if that solves problem.

Boot into system however you can, then open a terminal.  Enter the following command:

Code:

gksu leafpad /etc/X11/xorg.conf

(NOTE:  the "X11" part is an "X" and two number 1's, not lowercase letter L's.)

Enter your password when asked for it, then your text editor (leafpad) will open up the file /etc/X11/xorg.conf.  I'm assuming that the file did not already exist, so you will probably see nothing but a blank page when it's opened.  That's fine.  Just add the following lines (including the indented formatting) as shown into the leafpad editor for that file.

Code:

Section "Device"
        Identifier "My device"
        Driver "intel"
EndSection

Now save the file (File -> Save) and close the text editor.  Close the terminal and all other open programs (if any), then reboot the computer.

If we're lucky, that might have been the problem.  Confirm after reboot that the Intel driver now shows for the graphics card by entering this command in a terminal:

Code:

inxi -Gx
