Second graphic card was crashed (ATI Radeon Mobility x1400)

[Mario]

Few weeks ago I got a screen error (horizontal red and green horizontal
lines)on my laptop (Fujitsu Siemens Amilo Pi 1536). After few days, restarts
and driver reinstall laptop screen and external screen was black. I bought
second graphic card on ebay.com, implemented and it works fine for a few
days. Then I got a small errors around a mouse pointer. Few restart,
upograde ATI center catalyst software and become even worse. Now I got half
a laptop screen immediately, lost of vertical lines on external monitor. I
tried to put back old card, but the screens are black, as where. Obviously,
my laptop kills the graphic cards. What can be a problem? What can I do?

It may be the LCD panel, not the video card. See if you get
correct output hooking up an external monitor to it's video
output port (assuming it has one).

Like I wrote: external monitor also have an errors.
Obviously my laptop ruin the graphic cards. But I can't understand why? If
it's power problem it will also ruin some other component, if it's
motherboard problem it is pretty strange to me to permanently kills some
component.

I don't have much or any expeience with laptop, but it sounds more like
either the LCD itself gone bad or the connection. Or it doesn't sound like
video card to me.

Other than that I have never looked inside the laptop to know what inside
it. The onlything I have done was upgrading 2GB memory to 4GB, and looked
at the battery.
