From the sound of it you just have a compatibility video issue that is common. I haven't experienced them so I can't provide guidance on troubleshooting, but this could also be a problem with the CD itself. It was asked previously, but not answered. Did you verify the md5sum of the downloaded iso file against the md5sum listed where you downloaded LMDE from? If there are any errors in the downloaded iso the md5sum output will not match, confirming the errors and making the downloaded file useless. That's a critical first step after downloading an iso and there are directions throughout the forums on how to do check it if on Linux, Windows or Mac. I don't recall seeing what OS you are currently running.
Also, once you confirm the md5sum, you can still have burn issues. It's imperative that you burn as an image, not data, and that you do so at the slowest speed possible on your machine. This prevents errors during the write process.
If you've done all that and still can't boot then I'd lean heavily toward something with the video and search as suggested above for others that overcame the same problem on their machine.
