Trouble Initialising Direct3D

[The Berzerker]

I have a Radeon 9800 Pro and I've been having some trouble lately
initialising Direct3D. This occurs with either the latest Omega Drivers or
the last few releases from ATI.

Any Direct3D application that needs to be fullscreen will fail to run, and I
must restart the computer (and then I may use Direct3D flawlessly). I'm not
sure of the cause of this... but I've noticed that any games requiring
OpenGL will work perfectly when this problem occurs. I've been playing a lot
of Doom3 lately, and I'm thinking that perhaps it's this causing the
problem. Either way, I'm still looking for a fix. Anybody know what to do to
make Direct3D function without a restart?

A way to re-initialise it? Shut something that is apparently using it, which
would prevent others?

I know I'm being rather vague, but I figured there might some obvious way of
fixing this once it happens. So I posted.

Thanks for any help....

Couple of thougts. I had to update all of my mobo
chipset drivers to prevent video crashing in Solidworks
when we switched from Win2k to XP. I think I see it
happening again as we go to SP2.
Also, believe it or not .. newer mobos at the "revision"
level of the same mobo type, have chipsets that are
meant to be used with newer "revision" cpu(s), even if
the cpu type seems to be exactly the same. Why I'm
saying all this ?? ..... isn't it true that D3D is the hardware
subsystem underpinning directx ?? That seems true from
what I read about it. Go check the web for the latest
chipset drivers for your mobo .. esp the video or AGP
drivers. Poop has it, the new drivers are more directx
compatible, and your old drivers were already OpenGL
compatible.
