So I am using a laptop and ive been using it for a year or two now and its been running just fine. Recently in the past two days whenever I full screen a YT video (which btw I always full screen videos, its a habit) and watch it for a while my computer screen turns black I see the mouse glitch out a few times and it shows the loading cursor and then my computer just goes completely black and I cant use it so I have to turn it off then back on manually. This happens randomly and not always on every video. The laptop specs will be below but I can run things just fine and I am pretty good with closing a lot of the background programs. I haven't noticed this with really anything else cause I watch a lot of YouTube. I have no idea why this is happening and I really need this fixed.
Laptop Specs:
CPU - I3 5005u (2ghz, 2 cores, 4 threads)
GPU - None
Ram - 8gb
HDD - 500gb (353gb of free space)
