I didn’t properly connect the power-brick to my new Asus Tuf Gaming A15 laptop. As a result,the power to the laptop kept connecting and disconnecting and the laptop was constantly switching between silent and performance mode .After connecting and disconnecting for a few times , the screen turned black for a split second and went back to normal without any issue . I fixed the powerbrick and the laptop is working normally but how do I know if my GPU or any components are damaged or not?
