if the driver is OK (check in Device Manager), the next step is to think the card is broken and needs to be replaced.
I bought my dell laptop one month ago,it worked fine until recently.
First,my game "sims 4" was working fine but then it sarted to lag and it took 5 minutes to start it.
Then a movie was lagging too when I played it.
Then we decided it must be a problem with vga
My brother did a check and found out that my nvidia vga doesn't work when I disable intel.
Can someone pls help me with this?
