Webcam on Alienware m15x

my webcam on my alienware m15x has recently stopped being recognized. i went into device manager and tried that but it still isnt working with any of my webcam chat programs. I tried to do a system restore and that didnt work at all. i need suggestions on what i can do to fix this issue, im thinking i might have to just do a full wipe and use the restore disc that came with the laptop but thats my last resort. please help. email me with your suggestions.

Tried what?

Honestly I'd suggest just calling up Dell support (Look in the pouch of information Alienware bundles with their machines). Alienware costs for a reason, and one thing that at least they don't try to get out of is supporting their hardware.

If you don't want to do that, can you give us a little more information such as what application it isn't working in? Full wipes are last resorts.

well i was using Cyberlink youcam a few days ago and the webcam was working fine but now i open it and get the different wide colored lines like you would see if your tv went off the air. im an avid computer gamer and so i know quite a bit about these kinds of computers but it just stopped for no reason. i aquired this off of a trade, so i dont have all the paper work, just a few discs.

I'm trying to understand the lines you are speaking of. My best guess would be either a driver issue - but since you have some understanding of these things we can assume you have already installed and reinstalled - or a physical problem with the device,

the lines i am seeing are vertical lines and they are solid colors similar to ones you might see on your television.

im not sure what to do.

please help me

the image im seeing is similar to this one http://www.zazzle.com/tv_test_pattern_color_bars_photosculpture-153102776483174314http://
