We bout a Toshiba notebook and connected it to the TV but then when it was first turned on in the morning it would soon crash to the blue screen of death but then after that run good for the rest of the day. My wife said to send it in to be fixed but for a few months I was sure I could eventually fix it.
After downloading drivers and patches and surfing the internet, I started messing with startup and configure files and my wife said: you don't have a single clue what you are doing. And I said this is true but as long as you keep a backup then it will be okay.
Finally on Saturday the notebook would not start at all. So I switched it with my wife's computer. That fixed it.
