My sons computer is getting a direct 3D Acceleration failure when running the Direct X Diagnostic Tool.
He has a NVIDIA Riva TNT2 Model 64/Model 64 Pro driver file version 22.214.171.12473. I just upgraded it to 126.96.36.19984, but it didn't fix that problem. When I tried installing the latest drivers, it says that it didn't find anything compatible to upgrade.
There are many of his games that do not work because of the 3D not working.
Is this a sign of a bad video card or do I need to upgrade to the correct driver?
Some time ago I had this same problem and I thought upgraded the driver and it worked; but later had to reformat the drive and we are back to the same problem. If it's a driver issue, how do I go about finding the correct driver?
Thanks for your help!
