Go to CONTROL PANEL, SYSTEM and SECURITY, and select DEVICE MANAGER under SYSTEM options. Go down the list to IMAGING DEVICES and click to see if your webcam is installed with a yellow symbol indicating a problem.

If you have a problem OR if the camera is not there, try reinstalling the Device Driver. Go to your computer manufacturer's web page, identify your system, click support, and device drivers. DOWNLOAD and REINSTALL the device driver for your camera.

If this does not work, you may have a hardware failure and need to replace the camera which is usually very inexpensive. Look for it on eBay rather than the manufacturer's web site.

Under View tab, there is a Hidden Files and Folder; click the Show Hidden Files and Folders .

Do you have access to a volt-ohm meter? Look at your power supply, it says what the voltage needs to be. Does it have a green led & is it on?
To chk using a good meter, dis-connect your power supply from your pc & from the wall plug. If both ends are not connected you will not got shocked if your in your home, sitting down. Turn the meter dial to the "ohm" setting & begin with the R X 1 scale, place the black lead to the outside edge of the cable, place the red lead to the center pin, if the scale meter doesn't move, then try each of the other scales. After you finally got "a reading", do the same to the end that plugs into the wall. They will be different, but you do have to have a reading on both ends, or the power supply is bad. if all is good, (got a reading), plug the power supply back in to the wall & turn the meter to the dc scale & voltage to the 10 to 50 vdc setting. Very cautiously now, place the black lead on the outside edge again, & the red lead to the "tip" of the pin in you pc end of the cable. DO NOT ALLOW the red lead to make contact with the outside edge of the cable or you will short out the power supply! If you have the proper voltage, (usually 16vdc to 20vdc) the power supply is ok & you'll need to take the pc to a competent repair place to get a quote for repair. BE CAREFUL!
