creen goes black

Sometimes, when i start a game(Call of Duty 2)or try to change the resolution or refresh rate, my screen goes black.
The computer is on, but screen is black(and the monitors power led goes to orange)
Only boot helps. I use Nvidia's newest Vista drivers.
What can i do?

Are you trying to switch to a video resolution that is outside the capabilities of your monitor? If so, this may occur. And, if this is what is happening - you are lucky that a reboot solves the condition. For most people, it will not.

Im using 1024 resolution and 85 Hertz(my monitor is capable for these settings) And i think i solved this problem. I changed Vista's Aero skin to a Windows default and now, the black screens are gone. Dont now why this helped.
