I suppose it is a unsigned drivers issue.

Go to Run and type: sigverif and follow these instructions: (if you can still access your Windows environment).

When you have found unsigned drivers, you need to decide whether to remove them or to disable driver signature enforcement in "Advanced startup". The easiest way to go to "Advanced startup" is to create a shortcut on your deskop: Rightclick on your desktop, create a shortcut. It will ask for a path. Type in "%windir%\system32\shutdown.exe /r /o /f /t 00" (without quotation marks). Click continue. It will ask for a name. Call it "Advanced startup" and finish ! Then click on the new shortcut.

For detailed instructions and if you can't acces Windows, try this:

You can very likely alos disable signature verification in the BIOS (depending on your model).

But all this will only work for once to allow to install an unsigned driver. At the next reboot, driver signature enforcement will again be enabled automatically by Microsoft !

At your own risk !

(But the errors in your dumps could also indicate other things: did you recently install more RAM. Then make a RAM test (find Memtest86 on the net, download it and put it on an empty USB stick and boot form the stick). But accord to the Net, there could be other reasons too: a virtual machine for instance).
