Sounds like there has still not been found the ultimate solution to this.
I am running constantly into this problem and tried many of the suggested work arounds that sound like a suitable workaround.
e.g. ContentBrowser -> realTime, PowerManagement are things I have tried.
Cleaning Ram and graphic card contacts is one of the tings I did not and will not try. My laptop is brand new, don’t see the need for it.
It is really mind blowing that things are so unstable with a pretty beefy machine like the Aero 15x or the MSI GS67.
