Acer Aspire 5755G Gaming Laptop i7

the laptop has two graphics cards or one card and one integrated

and i think my computer has been using the integrated and not the nvidia card

i checked under the computer rating....

and it said that intel graphics and only 2gig ram

my laptop is 6gig ram on the nvidia card

i read it might be out of date and so i managed to get it updated and my computer graphics rating went from 5.5 to 6,7

but it still appears to be on the intel graphics and not the nvidia

it says 6 here..

could someone advise me on how to fix this?
