If you have a screen issue you should connect another screen to the laptop. This should refresh the laptop screen and the regular screen from what I saw it will only turn two times off temporarily. This may apply to Windows Vista and Windows XP. Also it might apply to Linux but that’s probably less likely. You can disconnect the regular screen after.
Edit: It seems it was because I had two drivers installed. Check your device manager. I removed the duplicate driver today.
Edit: This time I think it’s finally fixed , Windows 7 will eventually detect if it can’t start up. Then it will let you go into repair mode.
Edit: Toshiba is just a piece of crap.
