windows explorer lagging

[McCloud]

Recently I've been experiencing serious lag overall.. especially in windows explorer, opening windows and navigating. 

 

With software as well (Adobe Lightroom, Premiere, After Effects). 

 

From a system like this, I'd expect everything to run silky smooth:

AMD Ryzen 7 at 3,8 Ghz

16GB RAM

GTX 1060 6GB

Intel NVMe 960 Evo M.2 SSD

 

Is there any way to find out where the problem is ? 

 

In task manager, everything seems to fine.

Made any software changes lately?

Ever run CrystalDiskMark?

nope

stock was 3.0 

But it's OC'ed from the very start and it was running great just until 1-2 weeks ago.
