Question about HP Pavilion dv4000 Notebook
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!
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!
