    I didn't use DDU but I did reinstall the GPU driver and checked the box that made sure it was a clean fresh installation.

    Try again from scratch with DDU, and run something like HWInfo so you can see power usage, temps, and clocks, post a screenshot of the HWInfo sensors tab after running the Firestrike bench.

    Usually the preset should be enough, but you can tick all 4 boxes belonging to nVidia, DDU should be run in Windows Safe Mode.

    OK, so I have uninstalled using DDU. Then I went to the NVIDIA driver webpage and chose the driver for the 980m which came up as 436.30 and the installation is failing. I then tried to install GeForce experience which installed fine but when GeForce installs the graphic driver from within the software it is version 388.13 which is from back in 2017 and it says that is the latest up to date driver. Now the laptop feels really slow and unresponsive at times.

    I'd try disabling driver signature if you haven't already. Just in case.

    Strange. I'm guessing that a modded driver inf combined with disabling the signature will work.

    Just on this one, doing a 'clean installation' doesn't remove the old driver. It just resets any Nvidia settings you've changed from default. DDU is needed for this.

    I did use DDU in the end and it still didn’t work.
