Sorry for the delay in reply. I've been offline.
You don't need to use DDU. Only install the latest drivers provided by Asus for your device.
I also suggest not installing any other unnecessary third-party software (Could Ghelper or Armory Crate) and see if the computer works stable.
If your computer works stable and you want to install one of these software, first create a restore point.

If installing the software causes the system to become unstable, you can restore it to the point where it was stable.
