T61p has games not finding compatible video

[JaysonL]

I need help with gaming issues. I have T61p - 6457-A24, 3Gb RAM, NVIDIA Quadro FX 570M video which WinXP 32 shows as 512Mb (but Lenovo Quickpath says came with 256Mb). This is a recently purchased system from IBM EPP and has been refurbished. I strongly suspect the motherboard was replaced.
Issues are various games will not start, cannot find video card. Older Microsoft games such as Midtown Madness 1 & 2, Diablo 1 & 2. I think it has to do with Direct3d which those games use. Other games such as EA Battlefield 1942, Battlefield Vietnam, Insane offroad, MS Dungeon Siege LOA run fine.
Midtown Madness 1 & 2 give error on launch "No compatible video cards can be found". Diablo 2 gives similar error.
I am new to this forum, although I worked 20 years with IBM in IT support and worked on most IBM Thinkpad models from Thinkpad 600 & 770 systems through the T42p & X40 units.
Windows XP pro is fully patched, I re-installed DirectX and have tried a few different drivers for the NVIDIA Quadro FX 570M. Issues remain the same.

Have you tried the Omega drivers?

Yes, tried Omega drivers, same thing, BF1942 and newer games run fine, older games using direct3d (not directX) have issues, cannot find video etc. Microsoft Midtown Madness 1 & Midtown 2, Blizzard Diable 1 and Diable 2 will not play, cannot find video.

Did you try this: http://www.hardwareheaven.com/nvmodtool.php

It looks and is old, but works the same with new drivers.
Give it a shot.

@wehugheog, Thanks, but your link fails to connect. Can you repost your web link, or something, I cannot seem to gain access to this hardware heaven site unless I am already a member, ...

Nothing wrong with the link!

[wehugheog]

hm I can not see anything wrong with the link either. Also you do not need to be or become a member of that site to use it or the mod.

OK, for some reason, now the link worked and I have downloaded the nVidia driver modder. It will be a few days before I can give it a try. Thanks and I should have an update later.
