My xps L502x has a gt 540m video card, but when I check my device manager it only shows "Intel HD Graphics Family" under my displays tab. I bought this laptop new about 4 years ago and haven't had a problem till now. I hadn't used it in a few months and when I booted it up, I had windows updates waiting. I did the updates, but when it started back up and was installing them there was a problem and I got a message saying it was reverting back to previous settings. After I did that, I did the updates again and it seemed to work fine and that is when I noticed my graphics card issue, but not sure if that is when it began or not. I went into the bios and the card does not show up in there either. Is the card dead or is it something else?
