Solved Graphics Card Driver not Installing

Well, it all started when I noticed that my machine was lagging when showing the UAC prompt. It used to happen before, and it was gone when I reinstalled GPU drivers. The screen used to go blank and then turn dark, and the same when going normal again.

I was installing the drivers I already had downloaded and unpacked. It said the drivers were older than those installed on my PC. I thought, that's fine. I'll install them and later install the latest release. But the setup actually deleted the driver I had, but didn't install them again. Vista looked like a nightmare. I rebooted the computer, and it detected a plug-and-play device. It detected it fine, as nVidia GeForce 6150 Go, and things were fine again.

But I saw that the lagging was persistent. I installed the drivers I got with my PC when it was new. Again, the video card is not working. And after I reboot, the computer detects it as Standard VGA Compatible Device. The video card doesn't work, and nVidia Control Panel is gone. When I try to install the drivers, it tells that setup didn't find any compatible devices on the system and closes down.

System Restore is not working too. I downloaded the latest ForceWare, and it shows the same error. I'm not able to play any games, and even see the iTunes visualization. Nothing works properly.

download a driver cleaner and the correct driver from the manufactorers website, not nvidia as the "go" series are often only made for specific machines.
uninstall the card from device manager first and then the software from program features if needed, reboot in safemode then use the cleaner.
reboot in normal mode and install the driver when asked. that should install the card.
you may want to update directx at the same time as some video drivers and software may need some of its components as well.

best to turn off your security while installing the drivers as it may bug out the install.

Well, I do have the latest DirectX. And also, however I uninstall the drivers, the new ones don't install, as they say there's no device to support the drivers.

Oh, and one more thing... this problem is now fixed. I was going to reformat and reinstall the OS anyway, so I'm done with this forum.
