It is possible to change the graphic card in my Dell Inspiron 3521?

Well, my graphic card just stopped working, i can't play GTA, CS GO, not even Minecraft! And i went to the device manager and the graphic card was on, and with a! Signal at her front!

Not possible to change the graphic card. If it's dead, it's dead and your only option is to replace the entire motherboard etc, or buy a new laptop.

With that said, the! Can also mean something is wrong with the drivers. Have you tried to reinstall the GPU's drivers? Meh Buy a better pc if you can afford it. But if not then change the graphics hard As soon as possible.
