My computer was working fine up until 3 days ago, I only noticed the change when I went to watch something. It was working fine until 2 minutes into the movie and then my whole computer froze, not just the internet browser but everything, I left it for a while thinking it would return to normal but it didn't, it was still the same hours later. Not even the keys on my keyboard worked. I unplugged it as I couldn't shut it down, and when it restarted, it returned to normal. However, whenever I'd watch something the same thing would happen and I'd be forced to unplug it. Now though, whenever I do ANYTHING, such as uploading, downloading, installing, opening up applications (safe normal ones) it'll do the same thing and stop all together, like freeze. I even wiped everything off my computer, restarting the whole system or whatever it's called, and it seemed to be working fine but after a few minutes the same thing happened again. I've lost all my important files because of this. Also, whenever my computer reboots it won't start properly, the light on the side of the moniter keeps flicking orange and the same old ''no connection'' or whatever shows up beforehand. I've tried so many things but nothing seems to work.
