Hello, I have had Windows 7 for a couple months or so, and have had no issues except this one. This comes on without warning. I am either watching a video online, or just surfing the web. This happens, makes no noise of any kind, and I have to manually shut down. I thought it was something with a video driver, so I uninstalled and reinstalled that. I also did the same with my audio driver. What could this mean? I have win7 ultimate.


HELP!
