Large GPU fluctuations. Please help!

So i have been having trouble with my graphics card and have opened a few threads already regarding it. 
It is a RTX 2060 mobile and it is not performing well. I have pretty much tried everything at this point and have made a few conclusions.
 

- the graphics performance is weak and is not being improved
- each time you do a fresh install of drivers the card performs normally for about 6 seconds of use before it reverts back to dodgy state
- the drops i am talking about are not small drops but drops from 140fps in Unigine Heaven Benchmark to 12-21 fps
- while in dodgy state it averages 2500-3000 in firestrike
- dodgy state refers to the gpu's behaviour shown below when underload
- dodgy state has not been observed once when doing a kombustor stress test, although fps is around 42 with x16 tesselation at 720p resolution

I can attach more stuff if needed. Any help would be greatly appreciated

these two images show gpu some stats when running unigine. Something weird i noticed was that when i went onto another application and then maximised this again, it would temporarily stabilise (1-3seconds) and behave like you would expect. If you look at gpu 1 usage you will see a few points of extended max. These longer maxima are the maximising of the window. if you look at the last quarter, you will see one extended maxima and then jagged hell. This was the point where I maximised, left running, then closed. Hopefully this will help you interpret the images.
