Question PC and Applications become inactive

[orangeme]

I could be watching something on YouTube, the video freezes but I still hear sound, I can pause it and click other things but I can't see it happening visually, same thing with every other application, everything is unresponsive including the windows "sleep, shutdown and restart" options.

I've had this build for around 3 years, this started happening maybe a week ago.

Sorry to bother, any ideas as to why this is happening by any chance?
