Webcam driver for Nitro AN515-51

clark13542

My webcam just suddenly stopped working. If I open anything that uses it, the green LED light turns on, but the video is just black. Device Manager calls it "PC Camera", and lists a Microsoft driver dated 6/21/2006. Update says this is the current driver. Acer driver page lists nothing for the webcam. Since I can't identify device manufacturer, I can't go to their website and get any help.

Other troubleshooting tried - webcamtests.com sees my camera, but returns an "OverconstrainedErrornullnull; Object" error when I try to test it. I have tried uninstalling and reinstalling the driver. I updated to Windows 10 1909 since the last time the webcam worked, so I uninstalled that update, but nothing changed. I did take apart my screen two weeks ago to replace the back plate, but I have used the webcam multiple times since then, and not had any problems until now. 

I am doing a lot of streaming and web conferencing right now (aren't we all?), so this is a terrible time to have my webcam go down.
