scrolling blue and yellow lines on dell laptu

Specs: Windows Vista
Dell Inspiron 6400 laptop

After using DVD drive, closed down normally. When I switched on next day, got a blue line across the top of the screen and then scrolling blue and yellow horizontal lines, followed by blue lines interspersed with spikes of green and blue. Now the next day and when switched on seems to boot, getting as far as all usual icons appearing on the screen and then reverts to blue scrolling lines and being unresponsive to mouse or keys.
Have now managed to get to the Dell BIST troubleshooter by pressing FN and start. It showed the coloured screens with appropriate sounds but then reverted to the scrolling lines as before.
Any answers?
Thanks for any help anyone can offer!
