Lap top screen goes blank?

Question

When I power up my lap top, it works fine for about 20 minutes. After that, the screen flickers a few times, then goes blank, usually a blue-ish color. I took it in and had computer techs look at it, but they couldn't get it to do it again, claiming they left it on for 4-5 hours. After running diagnostics, they determined there's nothing wrong with it. They said I might need a cool pad, so I bought one. I tried it last night and the same thing happened after about 20 minutes. Any ideas? It's a Toshiba, bought in January, still has warranty remaining.
