My computer is relatively new (3-4 years), has a terabyte hard disk that I haven't even scratched the surface of, and keeps lagging horribly.
It doesn't crash, because the problem (from what I have been able to tell) is in the system that puts images on the screen, not the system that connects to the internet.
So far, the problem has only happened in graphics intensive games like Minecraft, and even happens when I play in offline mode. I know the problem isn't with the games themselves because a) it has happened identically in more then one game and b) when I start to do something else that requires the loading of a video, even on YouTube, the problem persists.
The problem always fixes itself eventually, although twice my entire screen has gone black for a few seconds, after which the computer gave me an error message that said something like "The device driver has failed and been recovered." I ran scans for errors in the device drivers and got a message that said (basically) error found, let me fix it. But the problem persisted.
When the lag comes on, I cant even walk an avatar in a straight line because my actions are out of sync so badly with the image that I am seeing. I think that my actions are being put through to the system all right, just not to the screen that I look at.
What should I do?
