Trouble when running game.

The the sound when running game told me that the game is running, so the error cant come from RAM. I think this is about the graphics card, the monitor display, or something like that.

After starting the game, you get a black screen but you can still hear all the sounds at (what should be) the login screen. Furthermore, you can alt-tab to Notepad, Firefox, or some other running program. Is this correct?

--> If yes, then maybe the game is trying to run at a (vertical) refresh rate unsupported by your monitor. So you'll need to determine that and enter that into the game's setup program. Consult your monitor's user manual for this information. (Or you could just blindly try 60 Hz for (vertical) refresh rate -- which could work because 60 Hz is the default for the Windows XP desktop.)

--> If no, then I really have no clue. Any idea is just grasping at straws.
