graphics chip

[Rusher]

What do you do if you think your graphics chip has gone bad? The picture on my laptop went all fuzzy last week, and now it won't turn on at all.

You can use a regular computer monitor to check it, plug it into the Vga port on the side of your laptops, If works fine with regular monitor maybe the problem is in LCD inverter

When an LCD inverter is going bad and needs to be replaced, the light to the monitor can either go out altogether, go out after a brief period of usage, or flicker on and off; the much dimmer image can sometimes still be seen on the screen.
