Whenever I start a virtual machine I get BSOD

[MeepsterNotchy]

The host machine is running genuine Windows 10 Pro, and the guest OSs on VirtualBox thAt I've tried are Windows XP, Windows 7 and Windows 10. Whenever I start any of the VMs, my host Windows 10 crashes with "IRQL_UNEXPECTED_VALUE." I will use these virtual machines for testing simple batch files I make, because I do not know if they will be irreversible on a real machine. Any help much appreciated.

Hi, did you previously have VM's working? If so, you have recently installed any new drivers? Check Windows Update History to see if any drivers were installed that you are not aware of.

Do you have KMSnano installed? If so, remove it and any software being used with it.
