Boot to SAFE MODE and if the screen is flickering, contact your warranty provider NOW before you have to pay for repairs.
Not a good sign.
Just to confirm!!
I have a Toshiba Satellite 5005-S504.
Win XP Etc. Two years old. No problems 'till now.
The Screen has started flickering and changing color, (sort of like Safe Mode VGA or a negative) and lines flashing across the screen.
Anyone know what is going on?
