Windows/File Explorer lagging/freezing

[Mr_Costa]

This is a very annoying problem I have in Windows 10. It has been like this for 2 weeks and after a lot of searching and posting in forums, I haven't got any fix whatsoever. I'll explain my problem:
If I open This PC (for example) icon on my desktop, all of my RAM and CPU will be used and it will freeze my Windows for 20 seconds or so. The same applies to all the folders I try to open. When moving a 100MB folder, it uses almost all of my RAM and disk. I have tried the following commands but none worked: sfc /scannow, chkdsk and DISM.
I have a HP Pavillion P6-2006pt desktop.

Please, if you think you know what's going on, please tell me, this is annoying as hell! Thanks.

I don't know what is going on but yesterday or the day before my computer was very fast at turning on and off and all apps were fast to open then crashed MS took some info and restarted my computer which after became slower, lag and some freezing. I did a pc reset which took forever after it was almost back to were it was before only for a few hours..
Back again with freezing and lag

Nobody knows what to do? :/ I don't want to go back to Windows 7 because of this because I actually like Windows 10.
