A solution to the computer's black screen due to high resolution

I used the computer, always used to 1024*768 this resolution, with a comfortable, but also did not have any problems.

Sister's children to learn computer, these days I have been at home in the evening to teach him some basic operations. There was a little bit of a problem last night, because I told him: you use the right key to the desktop "My Computer", in the "Settings" page of the dialog box, drag the top of the scroll bar, you can adjust the resolution of the display, and then I dragged backward, click the "Application", the computer suddenly black screen, reboot is still a black screen.

Call to ask a friend of the acquaintance, told me the reason: your monitor is not good, too old, too high resolution support. Solution: Into Safe mode to reduce the resolution, or to find a support for high resolution of the display switch, display the image after the resolution lowered, and then change back to your own monitor as usual.

Where can I find a high-resolution monitor, or go into safe mode? As a result, when the resolution is lowered in safe mode, the screen is still black after reboot. Call back and say there's no way to reload the system.

But I do not want to redo the system, a lot of things in C disk. So call another friend, he said: Silly child, do not want to reload the system can also ah, the graphics driver unloaded and loaded up on the line.

Then in safe mode to remove the graphics driver, reinstall the graphics driver and adjust the resolution, the problem is resolved.

It seems that a person has a mindset is not a good thing, some old people said that "no naughty children do not have a promise" this sentence also has a certain truth. Like me, with the computer for nearly two years, has been using this 1024*768, never thought of what will be the effect of the next tune, until the people show off when the problem. Dizzy.
