Laptop display problem

mjan

Hello, I'm hoping someone can help.

I've got a HP Pavillion ZD8369ea laptop, about 5 years old and running windows XP SP3. During it's life, I had to replace the screen due to loads of dead pixelated lines and, about 6 months ago, the ATI radeon X600 256mb graphics card died and I've been using the laptop with the on board basic graphics which is fine just to surf the web and write emails.
Now, yesterday, when I turned the laptop on, the display went all funny. The screen got full of colourful squares, lines, rectangles, etc. and the display settings got set to basic/lowest and can't be changed back. I took a print screen and emailed it to another computer but it comes out clear. I connected it to an external monitor but cant get any picture whatsoever.
I took a few pictures of how it looks like but cant post links as a new user. If anyone would like a look, I've posted them on photobucket under the user name mjan2. (If someone could post the links for me to make it easier for other users, I would appreciate).

Has anyone come across a problem like this and do you have any advice, please?

Thanks for your time.

P.S. - I've also tried starting in safe mode but it makes no difference.

This notebook is poorly designed. Extreme heat destroys the display, adding vertical lines that almost make it unusable. The HP customer service was awful.
WARNING: DO NOT BUY HP notebooks.

If it was mine then it would be time to bin it, try selling as spares on ebay

Thanks again, I just really wanted to keep it going for a couple more months and then try to get another computer after the xmas period.
If there's nothing that can be done, I'll take your advice and sell it for parts on ebay.

Edit: the vertical lines thing is exactly the reason why I had to change the screen a while ago...

One option would be to take it apart and remove then re-attach the ribbon cable for the screen in the hope its a bad contact. What makes me think that its beyond rescue is its failure to display anything on the external monitor you may have to use one of the Function Keys (F7 on my Vaio) to switch over to the external screen. Hopefully other's on the forum may give further advise!!!

Yep, on mine it is fn+f4 to display an external monitor so I was aware of that:p. Hopefully someone else can bring some other ideas to the problem.
Thanks again.

Anyone else have any ideas on this problem, please?
Thanks

Video memory or GPU. There is no other cause. If the graphics is using system memory it might actually be dodgy RAM so you could try swapping the memory sticks. You may then find the display is OK but your computer crashes which would confirm that as the cause. You can then work out which by putting one in at a time. Other than that, its a GPU/chipset/onboard RAM failure which is realistically a replacement mainboard or replacement laptops, breaking yours for spares.
