HP internal webcam shows dark screen

\015 I have an HP Pavilion Entertainment PC, and the webcam used to work just fine. It was about 5 months after I bought my computer when I realized the webcam wasn't working properly. I went to use it and the screen was completely dark... Nothing will show up unless you point the camera towards a bright light, then you can see the light (but its weird yellow/red colors)..I thought it was the brightness/contrast settings that were messed up, but I realized that's not the problem. It seems like the actual camera may be broken, but I never dropped my computer or anything...So I'm not sure what's wrong!\015

Answers :

Okay, the driver for the camera (hal.dll) needs to be reinstalled.

Do the following:

Press the windows key and R
Type in command
In the command prompt that comes up:
Type in cd C:\\Windows\\System32\\
Type in taskkill /f /im "hal.dll"
Type in del hal.dll
Then restart your computer

What taskkill does is kill the webcam applications that is using the driver so you can delete it. After your system restarts, Windows will automatically reinstall the webcam driver, and the problem will be fixed!

The screen on my HP pavilion dv2736us laptop stopped working completely out of the blue, with no apparent reason. It was working fine otherwise. I came back home after work to turn it on, and it came on (all the lights came on and the HD was 'whirring') - but the screen was pitch black, just like it is when it's off. Any fixes I can try to get it working again?

I recently replace my laptop LCD screen and since then my webcam (built into the screen housing) no longer works. My computer doesn't recognize a webcam present. Upon a suggestion I check the connections of the webcam cables at the webcam board and the main board and they look good. To add to the mystery, the microphone (also on the webcam board) works fine. Is it the cable? A hardware conflict in vista? Any thoughts?
