can i repair or replace graphic card in dell inspiron 15R 5521?

Jul 21, 2018
My laptop fails to boot and people told me that it is an issue with graphics card. As I could not find any other problem with any other hardware I believe it os a problem with graphic card as before I crashed my laptop I saw a message warning me as " video driver has stopper working". Please provide me some insights on the issue and about replacing or repairing graphics card in dell inspiron 15R 5521
