Here are my system specs:

2.8 Ghz Dell Dimension 4500
1 Gig of RAM
1 36Gig Western Digtial Raptor 10,000 RPM drive
1 250Gig Maxtor 7200RPM w/16mb cache
1 8x Sony DVD-RW
1 Lite-On 52X CD-RW
Sound Blaster Audigy 2
256MB Sapphire 9600XT

I've got the latest motherboard chipset installed. I've had this card for
over a year and I've never had this happen. I'm not using "the latest" ATI
drivers since ATI recommends having Service Pack 2 installed (which I do
not).

I don't understand why all of a sudden I would loose 3D acceleration
capability when its worked fine without having to do anything special for
well over a year.

Ideas?

Thanks,

Jeff

Hello,

I can't seem to enable Direct3D acceleration. I don't know what
happened
but all of a sudden I can't run any of my games. When I try to run
Unreal
Tournament 2004 I get the message:

"Please enable Direct3D acceleration. You can do this by starting
dxdiag
and enabling Direct3D Aceleration in the Display 1/2 tab after
installing
DirectX 8.1b (or later) and the latest drivers for you graphics card."

None of my other games will work eithere.When I open dxdiag and go to
the
Display tab, under DirectX Features Direct3D Acceleration says "Not
Available" along with DirectDraw and AGP Texture Acceleration. All are
unavailable.

I have DirectX 9.0c installed and an ATI Radeon 9600XT 256 video
card.

I've tried reinstalling the video drivers and DirectX too. I've also
noticed that 2d accleration must be suffering too since everything takes
much longer to redraw on my Windows XP desktop.

Ideas?

Thanks,

Jeff




Do you have the agp driver for whatever chipset your MB is running
installed? It would help if you gave more information about your
hardware setup.
