Are you sure?shut off because it is out of frequency
Do you know the vertical and horizontal refresh values for your monitor?
You may be able to fix this
When the live CD starts up press F6 and delete the "quiet splash --" ending and type in "break=bottom", then boot with this. If you end up in a "busy box" or so, reboot and type in "break=top" instead.
One member of the forum reported that "break=button" helped - this is really absurd, but worth mentioning.
You should end up in a regular CLI (terminal)
When you get to the prompt type in the following:
chroot /root nano /etc/X11/xorg.conf
Note: there has to be a space between chroot and /root and also spaces between /root and nano as well as between nano and /etc. Please note that the X in X11 must be a major X
This will let you edit your graphics configuration file.
Find "Section Monitor" - it looks like this
Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
Horizsync 30-70
Vertrefresh 50-160
EndSection
Make sure that the horizontal and vertical refresh rates are within the range of your monitor
Once you've done this press Ctrl+x then y then enter to exit the text editor
This will bring you back to the command line, simply type:
exit
and nothing else
and you will continue booting
and all your settings are inherited to the new install not to talk of the data you saved
