I would suggest that because you have checked the cable between the monitor and the pc you have confirmed that the monitor is okay because you are getting the message that it is receiving no signal. I would unplug everything that you can including the power cord from any and all ends one at a time and plug them in again because I think your next move after checking for obvious damage is to take it to a technician. I am afraid it sounds like something is broken in the pc. May not be a big repair but may be it is. Hope it is just a broken wire. The problem is could be damage to your video card; perhaps when the tower fell it damaged whichever receptacle on the back of your computer you have your monitor plugged into. Usually there are several, with most recent cards having at least a VGA and a DVI.

If you just bought a new monitor you probably have the necessary cables to try using the OTHER one. The impact of the fall may have caused the connection between your video card and your motherboard to come loose, or (and this is HIGHLY unlikely) caused the plug from the power supply to your video card to dislodge - it would be the only wire running to the video card. Unplug everything, open your case, unplug the power connection to your video card, remove and reseat your video card and plug it back into the power supply. If it still doesn't work you may need to replace the video card. If THAT doesn't work, try it in another slot (most motherboards have more than one PCI slot, which is probably what your video card uses). If THAT doesn't work you may need a new motherboard, and it might be a simpler matter just to get a new PC.

Notes:. If you have more than one webcam, all should appear in the drop-down list. If the camera doesn't appear in the list.

Is your camera plugged in? If you’re using an external instead of a built-in webcam, make sure that it’s plugged in and turned on. If it’s connected to your computer by USB, try plugging it into a different USB slot. If you’re using a USB hub, try plugging the camera directly into a USB slot on your computer instead—and try disconnecting other USB devices. Is your webcam installed correctly? Check that your camera is listed and enabled in Device Manager, even if you’re using the computer’s built-in camera. To open the Device Manager.

In Windows 10 and Windows 8 desktop, tap the Windows logo key ( Start) and type Device Manager in the search box. If necessary, choose the administrative tool from the results. In Windows 7, choose the Windows logo key ( Start) Control Panel. In the View by browse control items, choose Category. Choose Hardware and Sound, and then under Devices and Printers, choose Device Manager. Under Imaging devices, check that your camera is listed.

If it's listed, make sure it’s enabled. If you see a Disable option, then the camera is enabled. If you don't, right-click and choose Enable. If it isn't listed, or if there's a question mark or exclamation mark, you’ll need to reinstall the camera.

You can find the latest drivers for your camera on the Internet. Searching for the camera model on. If the camera shows up in the list but doesn't show preview. Is another application using your webcam? Close any applications that might be using your webcam, including video editing software, virtual camera software, instant messengers and Internet browsers.

If your webcam has a light to show when it’s in use and you see it when you’re not in a call, then some other application is using your camera. Check camera privacy settings. Some cameras have 'Privacy' setting.

Choose Camera Settings and disable the setting. If you only see a solid black frame in video preview, your camera might have a physical privacy shutter. Open the shutter to enable the video. If video quality is poor—meaning that call participants can see each other’s video feed but the picture is too dark, blurred, or pixelated, or the picture freezes—the following tips might can help:. Check your connection If the video freezes, looks block-like, or has motion blur, it might be your Internet connection (or another participant’s Internet connection) causing the problem. If Skype for Business detects a weak connection, it'll reduce the quality to try and stop the call from dropping altogether.

Review our guide to. Improve the lighting conditions A well-lighted room can make a big difference with the video quality of your calls. If the room is too dark, your webcam will try to amplify the signal to make the picture brighter, which reduces the video quality. Also if you have a window(s) or a bright light source behind you, for example, your face will appear dark and featureless to the other participant. For best results, make sure there's enough ambient light, and avoid back light.

Check your camera settings In the Skype for Business main window, go to Tools Video Device settings. You’ll see what your camera sees in the window.

If you’re using your computer’s built-in microphone, make sure it isn't muted. If you’re using an external microphone, check that its plugged in.

If the microphone can hear you, the blue speech activity indicator bar will move up and down (the farther right it reaches the better the signal level is). If you have more than one microphone and you’re not sure which name relates to which microphone, talk into each microphone in turn and check the blue speech activity indicator for movement.

Improve the speech to noise ratio. The best way to improve audio quality is by increasing the contrast between the sound of your voice and all other sounds around you. There are lots of ways to do this. In case of speakerphone or webcam move closer to the microphone. Being too far away from your microphone makes it hard for the mic to pick up your voice clearly. If you’re using the built-in microphone on your computer, make sure you know where it is and make sure nothing is blocking it.

For tablet devices, make sure your hand or a finger is not blocking the microphone entrance when you hold the device. Reduce background noise. Quiet spaces are best for audio quality because there is less ambient noise for your voice to compete with. Built-in microphones tend to pick up sound from all around. Reduce the volume of the playback.

If the volume of your speakers is too loud, or if the speakers are too close to your microphone, either condition can cause interference or echo. Turn down the volume on your speakers and, if possible, move them farther away from the microphone. Use a headset. Almost all the issues described can be improved or solved by using a USB headset.

All USB headsets work with Skype for Business, but the best experience is guaranteed by using a Skype for Business Certified headset listed in the.

On some headsets, for example, rotating the microphone boom up toward the ceiling equals “mute.” Consult the headset quick start guide or user guide for information about the proper operation of the headset.

Solve speaker or headphone issues If you can’t hear the other participant at all, or can’t hear them very well, there might be something wrong with your playback device (speakers or headphones) or settings.
