Flight sim computer. A very pricey gaming machine that, when its behaving is absolutely wonderful. However, it has what I am sure to be a video card problem. Out of nowhere the screen goes black just as if you had shut off the monitor. The video card fans go to 100% and the only way out is to shut down and start over. Research has shown this to be a fairly common issue with this model, and the remedy is replacing the video card. That's a $2800 item. It's under warranty and is going in tomorrow, we shall see how it goes.
