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.

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.
Hi there. Currently, Acer do not have any graphic card driver support for Windows 7, the reason is that they have to wait for NVidia to program a driver for Windows 7, then Acer programmers will modify the driver for their products. NVidia are currently working on drivers for Windows 7, but they will be for actual NVidia cards, i.e AGP and PCI/E. Drivers for laptop intergrated graphics, normally run anywhere between 6 - 24 months behind the general manufacturer's release.
If you follow this link to Microsoft, it does explain the risks of running Windows 7 beta, including, printers, video cards and other hardware that may not work.
Can you give me more information on this? What this is your onboard video display. The drivers are either not install, if you have a like high end graphics card built in. Now on some laptops, you can get from a separte video card not solder to the main board. This is good, so if the brand allows it, then you or who ever has it next can change out the video from a better or a replacement. Still need more information to help with your problem
