Hey
I Bought an HP envy notebook recently from ebay
Core i7
16 GB Ram
2TB HDD
Nvidia 950GTx
Here is the deal
I have windows 10

When I play videos on the default windows 10 video player it works fine

but when i open the same video files using any other players(VLC GOM KM ) there are glitches (green pink and black dots and lines) while yhe video is still playing in the background

The same thing happens when i am playing FIFA games

I dont know what is wrong or what i shud do to fix it

Please any kind of help os appreciated
