Not much to discuss from the dumps. A BitDefender driver does seem to be a potential culprit; can you temporarily uninstall any BitDefender software you have? Replace BitDefender with Microsoft Security Essentials if it's your antivirus. Apart from that, we may need some help from Driver Verifier if the system bugchecks again: https://www.bleepingcomputer.com/forums/t/576333/driver-verifier-bsod-related-windows-10-81-8-7-vista/

 

Cordially,

I will uninstall Bitdefender (yes it's what I use) and see if that makes a difference. How can you tell it's from Bitdefender??
