Your video chipset on your motherboard could be causing some problems. Your LCD could be going bad. Your backlight could be dieing (flickering), Try reinstalling your video drivers.

Can you be more specific? Are there certain times that this happens over and over? Do you access something in particular? Do you move your LCD?

If it were just your monitor, the machine should not freeze overnight. I would try different RAM in your machine if you can swap some out. Uninstall and reinstall your video drivers. Set your power options to turn off the monitor after a couple hours to conserve it's life.

In the end it may be a motherboard issue. I would call Toshiba and act on it if you still have warranty, or if it continues to be a problem, get a quote from them to fix it.
