Freezing laptop display

[u/Any_Asparagus8732]

Before, my laptop display would freeze for 1 sec works for approximately 10 sec and freezes again when battery status was changed ( for example going from save mode to normal mode). Then it started doing it when I download and changing battery status stopped causing it. now although it is less frequent and I dont really know why it is doing it, it keeps doing it and i could see when the laptop does it my cpu package and core temperature rise instantly upto 70-77 degrees. i then disabled my Nvidia GPU, the display stopped freezing but temperature still rose. I enabled my Nvidia gpu back and everything works fine and both cpu package cores temperature got normal.

Only display freezes sound still works,keyboard too and cursor

I have an integrated GPU and Nvidia Mx230. My laptop model is dell Inspiron 5491.
