Do I have a GPU problem?

[Reon28]

(I know it's the second time I ask this question but I really need an answear)

 

A few weeks ago I bought a Dell Inspiron 7567 with the folowing configuration: 

-7700Hq

-1050Ti

-1Tb HDD

-8Gb Ram

-FullHD Screen

I added on the M.2 slot an SSD from WD of 250Gb and I installed Windows 10. 

I had some issues like: I have an external HDD (connected on a USB 3.0) and sometimes the laptop didn't reconize it, I had to plug it in and restart the laptop so I could access the external HDD; I reinstalled Windows 10 on UEFI mode (as a moderator told me so).  Now I can use my HDD but sometimes when I am watching videos on youtube the image changes like in the screenshot I attached and also when the video is paused and I press 'space' to play it, it takes 1 second to start and, as much as I know, it shouldn't. It should happed instantly. Someone told me that I have a problem with the GPU. I tend to belive him because I don't have the same performance in games as others that made a review about this laptop and I have moments when the frames drop from 58 to 23.

I installed all the drivers from Dell's webpage and the last update from nVidia.

 

What do you think? Should I use the warranty and go to the service? Do I have a problem with the drivers?

Does it do it in anything besides YouTube?

This is in VLC  but only for a sec and only when I open it.

Hello again. I beilieve your new problem is the same as that I described in your previous forum thread.
 

Or probably caused by new windows updates. I heard about this problem in our social network group about 7567 dell. You better to fix a problem about I mention first because as I think this one is the aftermath. If you still want to use a fresh windows 10 build then you better to try this little program https://github.com/jobeid/TrayPwrD3 . This solves a bugs with Nvidia Optimus but as side effect it will increase your power consumption a bit.
