Windows 7: No webcam works on computer anymore

No webcam works on computer anymore

Hello,I have a very strange issue with my computer.
I have 2 microsoft lifecam hd 3000,one my dad uses on windows XP and one I used on win7 64 bit till some months ago when it suddenly stopped working .
The microphone works perfectly but I can't get any video either on lifecam(says no camera connected)or on skype/oovoo(stuck in loading camera-blank screen).
i plugged it in my dad's computer and its working perfectly so its not the camera's problem.
Device manager etc says everything is working perfectly.
I can actually get video from the camera on Silverlight Video tab.,but its not working anywhere else.
I plugged in my dad's camera,exactly same problem.Tried everything in the knowledge base,still same issues.Even ran sfc /scannow.

ANY help would be greatly appreciated as I don't know why a non-cheap camera is suddenly not working anymore,and NOR any other camera I plug in.

Hi and welcome to 7F. If you haven't then run the system file checker and you might need to run it 3 times
SFC /SCANNOW Command - System File Checker

I appreciate the advice,after many runs of the sfc tool and completely erasing the drivers from device manager and then reinstalling on every single usb port,the camera is finally working again.
