In all my years of dealing with computers, I've never seen this particular occurrence.
I switch it on and get the Toshiba logo screen, which it pauses on for maybe a little longer than usual and then I get a blue screen with columns of different coloured dark lines.
Then, it switches off.
I've removed the battery and replaced it. I've tried pressing f2, and f1, and f12 to no avail.
Alt+ctrl+delete restarts it when it's on the blue screen (and the issue repeats).
