If you can copy, zip, upload, and post a download link of your .dmp files I'll see if I can help. If they exist they are in \Windows\minidump and \Windows. \Windows would have a single file named memory.dmp which is usually the most useful but typically quite large. The ideal would be if you could upload all of the .dmp files from both directories.

If you can't get into Advanced Startup any other way it usually works to cold boot, as soon as the spinning wheel appears, force shutdown the computer by holding the power button down. Do it again. On the third boot it should go through a process that allows you to get into the Recovery options. From there you should be able to try a system restore.
