FINAL EDIT: Never mind, problem's been solved
Hi everyone,
First time poster - and I need some help.
Earlier today, Steam alerted me that my graphics drivers were not up to date. I went to ATI's site, but it directed me to the manufacturer's site (Gateway). I downloaded those drivers, but apparently I had the most recent one (in their database) already.
I did some browsing across the internet and found Omega Drivers. I uninstalled the ATI Drivers and CCC, and installed Omega. This did not work for me, so I moved to DriverHeaven.
I uninstalled the Omega Drivers, and followed the instructions for the Mobility Modder. (I installed the most recent ATI driver set for XP, 7-9_xp32_dd_ccc_wdm_enu_52443). It seemed that all was going well. I was playing Half Life 2 and it was running fine - and then all the sudden, it crashed.
I tried to figure out the problem, and figured I'd run a DirectX diagnostics test on the video card.
I got this error message when I ran the "Test Direct3D" tests:
"An error occurred while setting your display to 640x480 mode with 16-bit color."
This is what appeared in the notes:
The file ati2dvag.dll is not digitally signed, which means that it has not been tested by Microsoft's Windows Hardware Quality Labs (WHQL). You may be able to get a WHQL logo'd driver from the hardware manufacturer.
To test DirectDraw functionality, click the "Test DirectDraw" button above.
Direct3D 7 test results: Failure at step 39 (SetDisplayMode to 640x480x16): HRESULT = 0x80004001 (Not implemented)
Direct3D 8 test results: Failure at step 8 (Creating 3D Device): HRESULT = 0x88760827 (error code)
Direct3D 9 test results: Failure at step 8 (Creating 3D Device): HRESULT = 0x8876086c (error code)
Computer Specs:
Gateway M285-E (Tablet PC)
ATI Radeon X1400 (256 MB)
1024 DDR RAM
Dual Core 1.8Ghz processor
Windows XP
Do these errors mean anything in particular? Would it be best to download a driver sweeper, do a clean sweep, and then reinstall the most recent drivers through the Mobility Modder?
Any help would be greatly appreciated!
EDIT: I rebooted, and now all the Direct3D Tests are working fine again. Anyone have an explanation for why I had the errors earlier? Is such a thing normal with the Mobility Modder or should I look into it?
EDIT 2: Went back into the game - 30 seconds in, I came upon polygons that were shaded all wrong as the game started skipping. I may attempt to do a clean driver sweep, and then reinstall the Mobility Modder.
EDIT 3: Back to the original drivers. Another error while playing HL2. Maybe the engine just hates my video card

. Anyone have any suggestions as to what I should do?
Thanks a lot,
Hydro
