Disk and Memory usage spikes in windows 10

Hey, I've had this problem where my disk usage would spike to 100% before going back down to like 2%. I looked at countless forum posts and different sites and I found something which was a temporary fix, which was turning off tips about windows...
That worked for a while, and it just makes the intervals in-between the spikes longer, and now my memory has started to spike pretty high to about 99%, and wont come back down. When it does this I have to do a hard shut down as my pc just slows to unusable...
I also tried disabling ndu.sys in the registry, which didn't help either
I know it is not my RAM as I have tried it with other RAM and I still get the problem...

I am thinking of just restoring my PC back to Windows 7 soon if I cant get this fixed.

Thanks :)

So called "Memory leak", drivers, specially WiFi and BT seem to cause that most. Can't you see in task manager what takes most free RAM ?

nope nothing in task manager...
