I have just realized, you are correct, it has an inbuilt (integrated) video card.
It's very difficult to replace those chips and the entire motherboard might need to be replaced.
I don't know how old is your laptop but it just may be much more advantages for you to purchase a new system than having the one you have repaired.
All laptops with integrated (built in) video or sound cards are not advisable. They have a lifespan, that mean that after a certain time, they are programmed to fail to make you buy another.
I would look into HP
