I've been having problems with my Toshiba Satelite L50D-C-12X. The laptop freezes whenever I watch netflix etc while plugged in to HDMI. It becomes completely unresponsive, I need to long press the power button to force it to shut down. It only happens when it's plugged in to my TV through HDMI.
All updates both windows and toshiba are up to date.

The laptop is only 3 months old, Processor AMD 10-8700P, it runs windows 10 64 bit

Can anyone please help me fox this??
