Yesterday, I was watching Youtube videos perfectly fine. I made no changes to my computer in the slightest. Today, I was in the middle of watching a ten minute video when the computer froze, the screen went black, everything in the browser had to render itself again, and I am alerted that my computer recovered from my video card crashing. This has occurred in the past, starting about a year ago and thankfully it hasn't been consistent. I am using the latest drivers. I don't know what could be going wrong.
