open a command prompt and run

sfc /scannow

press enter and let windows find and repair any missing or corrupt windows files.

if that doesn't work then run a memory test.

Sometimes, when the keyboard, mouse or touchpad are not being used, a laptop put itself into "sleep mode". It does not understand that you are listening to music or watching a movie
