DirectX problem: Black Screen

[codex]

Hi there,

ive got a problem with one of my games, which causes a black screen after starting it on a friends machine.

On my pc its running perfectly and also on a lot other PCs too. But only ony PC shows up a black screen, without entering the menu of the game.

The PC, on which a black screen is displayed, has a 8800 GTX with the newest drivers installed (my PC also has a 8800 GTX, so thats shouldnt ne the problem). The OS is XP/SP2, with the newest DX installed.

BTW. the game uses Managed DirectX and .NET 2.0 (also installed on each machine)

After googling around, Ive read that there are also a lot of other games, which have the same problem on several PCs. Some guys told me, that the reason could be the refresh rate of the monitor.

If anybody knows, what the reason could be ... well ... then help me plz

If you need more information about the PC with the black screen, just tell me

Thanks a lot
cdx

Is black the color that you use to clear the backbuffer? Try changing it to red and see if you end up with just a red screen. It is possible you are not loading your textures/models correctly and it works on your box, but not on your friends.

Changing the

backbuffer.clear(color.black);

to

backbuffer.clear(color.red);

could help narrow down the cause.
