The other night I was on youtube watching some readings of biblical verses for my bible study group. When I clicked "play", the video started flickering and the browser minimized and maximized several times. I shut down my computer and turned it back on. I played a random music video and it was fine. Then I tried to open another (different) christian video and the same result occurred. I'm not sure why this cybernatural occurence is happening. Can someone give me advice??
