DirectX 10 - DxDiag DEP crash

A

Aditya Krishnan

Hi, I've been having a problem with DirectX 10. I ran DXDiag to check my D3D
settings and while it was doing the driver gathering thing, DXDiag crashed
and Vista said that DxDiag was shut down due to DEP. I have disabled DEP for
all programs except Vista essential services. Next time I tried it said there
may have been a problem accessing DirectShow and would I like to skip it.
Selecting No gives the same crash again and hitting Yes makes it ok except
there is no option to test D3D under the Video tab. How can I fix this? I
have a Packard Bell Easynote laptop running Vista Basic with 1 GB of RAM and
an ATi Radeon Xpress 200M video chip.

Thanks for your time!

No joy. It says "This program must run with DEP enabled" etc etc. Actually,
the reason I'm after this is because recently I've been trying to play
Half-Life 2 Episode 1. At the same point in the initial parts of the game, it
crashes out with an internal engine error: IDirect3DDevice9::present() error.
This is a DX API, if I'm not mistaken. So I ran DX tests with the
aforementioned results. Strangely enough, from my understanding, this
function is a very important part of all DX-compatible apps. But I'm able to
play most games (e.g. C&C3: Kane's Wrath, UT2004, Halo 2, Gears of War) with
no problems and very acceptable performance. Is it due to Vista? Will
switching to XP help?

Have you tried the updated ATI drivers here?

Failing that, you would want to get the DEP event analyzed using a
debugger...
