Laptop hangs up for 3 days?

Scarring Community,

For 3 days, the laptop is already the 8th time z.b look at the Netflix. I can't open, close or do anything anymore. It can only be switched off with a long press of the power button and then it works again. What could that be?

Defective, missing or incorrect drivers, defective hardware, overheating, harmful or faulty software in the background, depression or refusal to work.
