4) memtest = no problems

5)Clean install Windows 10, Steam, FO4.

Have you tried backing up your saves and starting a new game with no mods, to test if your mods caused save game corruption?

I'd personally not go anywhere near that amount of mods before the GECK is available. The game is still too immature patch-wise as well.

300 hrs without problem then update, what update? Windows update, driver update or beta update?

Have you checked for corrupted saves by renaming the save folder?
