It happened a couple of times but one time i was just surfing the internet on chrome, probably had winamp in the background(no big programs really) and it just started being unresponsive. Like the task bar would freeze up, if i moved my mouse over the icons it wouldn't even show any animations of lighting up or whatever it does. the task bar would like turn to a color to show that it isn't responding and have a spinning circle on my cursor.
Today i was just watching Netflix the whole night and all of a sudden it starts freezing up a couple of times till it actually did. It said the Silver light Plugin(Netflix) stopped responding but when i got out of full screen, everything else wasn't responding either. Like chrome Would still be functioning properly and every other program as well but windows would just hang and the task bar would go unresponsive.
That's when i try shutting down from task manager(Shutdown.exe ^^).. some how i got that to pull up(sometimes Nothing would come up at all) but everything else is dead basically besides programs. and to add to that, chrome would work but i wouldn't be able to go to any website it would keep spinning at the top.
