Dave just leave the new GPU in the PC,
- start Win with F8 pressed to safety mode ( now Win uses his hardware drivers! no NV!)
- now uninstall all Nvidia software and delete any NVidia folders
- reboot
- now install the latest NV driver package available
hehe - so the hardware support thread is running into here too...
I found before that my machine didn't work in safe mode, boots normally [or if screwed, re-gained this via recovery console] but halts with safe mode. But after recent changes, I'll give it another go.
Did uninstall all the nvidia software/drivers that I could via control panel, then also ran DDU for good measure.
When that found the old Omega drivers for previous card, but didn't remove them; manually removed all referenced registry keys manually.
Tried nv driver that came on CD, then the latest, then an early one.
GTL runs fine, but some GPL still fails to start in OpenGLv2. I think D3D may have sort of worked, but with resolution limitation/pribluda issue.
I did download some other opengl game to test & that also fails to get started.
I'll give it some more time tonight....
Bloomin' PCs... getting too old for this stuff...
