Games crashing, no error message.

all my games are crashing to desktop, its incredibly annoying. I have the latest gpu driver (gtx 1060 6gb) did a fresh windows 10 install, cleaned the cpu (dust, etc) checked for temp problems, and nothing seems to work. A few games that have crashed: fallout 4, just cause 3 , witcher 3, overwatch, pubg. I dont know what to do anymore, i invested heavily in this pc and it will be of no use if i cant solve this. can someone give me some advice? I've noticed that disk is being used 100% a lot of times, could this be related?
specs: gtx 1060 6gb, 8gb ram , amd ryzen 1400

even after the clean install, your drive is still maxed out at 100%?
when did it all start happening, Win10 1803 release?
does the PC crash if you don't play games?

Yes, still at 100%. I had to restore Windows last night, BDOS after trying to reinstall gpu drivers with DDu. I dont know if it was after win10 1803, was this update in august?
No , the pc doesnt crash if i dont play games, except for a few bdos due to a problematic USB network adapter.
Here is the log you asked, @jmarket
