So I'm watching a video on Youtube one day, all of a sudden the video stopped but I still heard the audio for 3 seconds after, but then the audio stopped. I then closed the Internet Explorer window and tried to open it again, but it couldn't open. I tried restarting my computer, but my computer wouldn't let me click the start button. i tried clicking it a few times and then the bottom part of the browser (the part with the taskbar and start button.) turned white and i couldn't click on ANYTHING there. I then tried clicking on something on my desktop, but then the desktop turned white and I couldn't click on anything! The wierd part about this is, it doesn't even happen at a specific time. It just happens randomnly. I then had to shut down my computer by pressing the power button. (I heard that wasn't a good way of shutting it off.) Someone please help, this is really annoying me since I need to turn my computer on and off and on and off so many times!
