This issue is usually caused by the graphic interface is not supported. You need to verify that you have the newer version of DirectX. To check the version number click START, select RUN and type DXDIAG to bring up the DirectX Diagnostic.

If everything appears to be ok, make sure the web cam driver is properly installed along with the video driver (video card). Please update the DirectX version of Windows if you got an older version.

If it doesn't work. try:

Check Properties of "My Computer> Hardware> Device Manager" you have any device with an exclamation mark or cross in yellow or red, respectively.

If you do not have anything like that, check if your webcam device appears in the listing.

If that doesn't work or there is no error on properties, another driver may be causing problems. you may need to go a little technical about this issue following the steps below:

1) install the drivers by disabling all the non Microsoft services on your system.
2) uninstall the web cam drivers.
3) unplug the web cam and need to reboot your system.
4) Then you need to go on your Start menu, then select Run and then type: msconfig and press the enter key.
5) on the General tab,you need to click on Selective Startup.
6) Under Selective Startup, you need to click on clear the Load Startup Items check box.
7) Then again click on the Services tab, then you need to select the Hide All Microsoft Services check box, and then you need to click on Disable All.
8) Then click on OK. Then it ask you whether you would like to reboot your system,just click on Restart.
9) Install the driver.
10) Plugin the webcam.
11) Restart the computer.

After doing all this still doesn't work, the issue may be caused by some kind of incompatible hardware.

Good luck!

I have a Nikon D80 camera. I somehow, unintentionally turned on the preview screen that shows all of the info. I don't want any print on my screen, no highlight, no RGB, nothing but picture.

If you were seeing a preview on the LCD monitor on the back of the camera, then there was something seriously wrong with the camera. Nikon did not introduce the LiveView feature until later models.
If you're asking about review instead of preview and seeing graphs or lots of data, press up/down on the multiselector to cycle through different views of your pictures until you get to one you like.

You need to configure the image settings - start with the focus lens, then the brightness and contrast settings that you can find in Options - Video capture.

I'm struggling using the webcam on the laptop- can't seem to find any options on it to get it going! Can you advise?

Download  AMCAP2, from here,

OK, install the "Driver" then plug in camera. Then run Amcap select your webcam from  the "Devices" tab, also check the Preview under the "Options" tab. You should be able to see an image.

If it is all OK, get yourself a good WebCam software and use that if you wish.
