Random BSOD on Windows 8.1

This is a relatively new system. However, I have had random BSODs almost from the beginning. My dump files date back to early January of this year. I couldn't find any common thread among them, but then I am just a laymen. When I say random I mean they happen at any time. Most of the time the crashes happen after I have left, and I am not working on it any longer. Although, it acts a server for a database which is problematic because of the crashes. I recently updated my display driver. I would be grateful for any input. Thank you.
