OK. I think I should explain the problem more. I did not change any of
graphic card or it's driver. The laptop just suddenly hangs and screen
goes to a green color fixed and collapsed shape image of the latest
windows screen with vertical dash lines. It needs a force shut down and
when it begins to reboot, the LCD goes on but I can just see a dark
black image. Even the boot screen (the first image in boot process) is
not shown but I can understand that the windows is starting up and the
laptop is working. In this situation, when I connect it to an external
monitor, a very bad quality image is shown and the rest is like to
which I explained before. Therefor I myself think that it must be a
hardware problem (because it doesn't show any image even boot screen
which is not related to any windows software or driver). But I can not
recognize which hardware has problem and what can I do? Please help me
if you can.

Re: More information about submitted problem.
You have a failing video card or chip, you will have to determine whether you have a video card or a video onboard chip... if it is a card, you can replace the card.. if it is a chip, you need to replace the motherboard, or attempt a "rebake" of the video chip to the motherboard.

In Windows, it just comes up with a message saying it will be clocked down, so you just click "OK"? if molex is not plugged. 1. You should install the driver for the graphic card so it wont show distorted images, Microsoft display drivers are not reliable in gaming you may experience distortions. 2. Plug the molex or 4pin power to your card and observe if you will encounter the same problem after doing step 1.
3. If not try to test another PSU or acquire a new PSU that is powerful enough to run the card - not using the power cable could damage all your system. Hopefully this information helps. Happy Gaming Thank you for using FixYa.
The graphics card is built-in on the motherboard and cannot be changed. If you are having problems with the graphics card, try re-installing the video driver. To test the video card, connect an external monitor to the video port on the T40 power up the monitor first then boot up the T40. The video information will transfer to the monitor automatically, provided the video card is OK.

Update your video card. To update download the latest driver of your video card from HP site. Copy and paste the link provided below to your URL and it will lead you to HP Pav dv2500t drivers. Choose the OS you are using, look for the video driver, download it then install to your machine.
If your screen do not include a driver cd, it is suposed to be a plug-&-Play monitor.
Maby your computer do not support plug-&-Play interface.
Try to download the driver by searching in google.
That can happen if your graphic card that do not have a driver either(see below).
If not working:
Download A driver for your graphic card.
You can check what graphic card you have by a software called "EVEREST Ultimate Edition"

There you are my friend, just follow the link and DL the driver there. Its for XP, if you need a different OS then just change the OS and click submit and then click drivers and downloads beneath that. Good Luck!
If you're really sure that the video card is ok and the rest of the system components are compatible with it, I suggest to search for a nVidia driver on www.guru3d.com ...they have modifyed video drivers to work better.Also, a directX 9.0c download would be helpfull......
