Laptop with broken screen How much?

I would like suggestions and look in local stores. I dont wanna buy a laptop from someone online. Sorry. But could be a good idea if you asked him about the performance on older games. Gonna make a list ofall laptops people suggest me.

Remove the screen for space purpose here its small desk and if the screen is opened it will hide my 22 inches lcd

 

Is my graphics card broken?

UPDATE: Please see here.

I have a Sapphire HD 4830.

When I boot into XP all is initially fine and I am able to see the desktop.

However, when I click on the start bar and navigate a few steps, I receive an immediate white screen of death and a total irrecoverable lock-up.

I am confused about what this could mean and I would be grateful for any suggestions on the best course of action to test and repair the problem.

Does this sort of issue suggest that the graphics card is irretrievably broken?
