LCD display goes blank after a few minutes

Dell Dell vostro 1500 notebook computer...

Specs: Windows XP, not sure
The display on my Dell Vostro 1500 goes bad after a few minutes of operation. At first it would get two images squashed on the screen, and then that would become 4, and soon the screen would be full of lines and unusable. I replaced it with a new screen that had a new inverter already attached. Now it still acts up and goes bad, but in a different way. It begins by getting vertical fuzzy lines that gradually expand until the whole screen is unreadable. An external monitor plugged in will work fine. Obviously some internal component is getting hot and failing, but which one? Is the video card bad? Is it integral with the mother board on this machine? In other words, can I replace the video card, or do I have to replace the whole mother board. Could it be something else? Thanks for any help. Bob H

I would say, in this case, that it is most definitely the video card. What you are describing is what we see most in the case of video card failure. I would suggest to buy a real old cheap 'n' nasty card and then try it in your system.

Let me know how you go! :)

Thanks for the reply. How do I determine if the video card is part of the motherboard or seperate? Could it also perhaps be a problem with the wire tape thingy that runs between the screen to the computer? That seems easier to replace. Thanks

The other part of this that doesn't make sense to me is that an external monitor works OK if the video card is bad. Any ideas? Bob H
