Make sure you have the latest drivers for your monitor installed.

Your windows video settings are for a monitor that has more capability (eg more pixels/finer resolution, higher refresh rate, more colour bits than the current screen can handle so it's spit the dummy.

Run your computer in safe mode (I believe that uses basic video driver) and set the video display options to a very low level, then re-start your computer again in normal mode, and set the options to the native resolution, refresh rate etc of the monitor. These should be listed in the specs that would come in the box with it (may be resolution: 1,680x1,050)

my epsom dx8450 just says cannot recognize ink cartridge but it is a new cartridge

try to boot on 10.4, and then introduce de 10.5 DVD. Then the computer will ask to reboot, but with good options.

uninstall anything you dont need is a good start. If, when you have done this, it persists, then reinstall the game. If it still does it, check if all the system requirements match to the RECOMMENDED, NOT MINIMUM. Some games wont actually work on minimum. Plus, some games dont work on some operating systems.
Please rate me.

did some thing change your refresh rates in the display section of your settings for the monitors? also have you tried to hook up another computer to see if it will display on the monitor? if nothing displays on the monitor then the monitor is faulty. if another computer (even a laptop) can display on the monitor then the video is set to high for the monitor to understand it. to reset monitor refresh with out a screen that will work you need to get into safe mode and reset the display settings to 60 hz and only 800 x 600 for starters and increase them until you cannot get a signal. if you cannot do this then a service shop will be able to assist you

Launch System Preferences from the ??Menu.
click on 'Displsys try changing resulution and brightness.
