After a lot of testing and formatting. I finally found out what causes the problem. It only happens if I use LAV and CUVID. But if I change CUVID to DXVA for example it works fine.
So that narrowed it down for me to being the nVIDIA driver. I tried many different nVIDIA driver but they all yielded the same result.
Finally, I tried the nVIDIA driver from my Notebook's manufacturer's website (Asus) and it works like a charm now!!
lesson learned: "Never bother to get the latest drivers always install the drivers from your laptop's manufacturer's site"
