Thank you.

All of your dumps are blaming the nVidia Filter driver. It's old and needs updating. Download the latest driver for your card from here and follow NVIDIA Drivers - Avoid Problems for the cleanest possible install.

Uninstall Daemon Tools, a proven cause of BSODs.

1. Uninstall Daemon Tools via Add/Remove Programs.
2. Download the SPTD standalone installer and perform the following steps.
3. Double click the executable to open it.
4. Click the button shown below.

   Information

If the button it is grayed out as shown in the image, there is no more SPTD installation on your system and you can just close the window.

Have you tried running it more than once?

Yes, I did.
I wonder this picture might helps?
