Hi guys! I can see that it's a more or less common problem, that some nvidia driver won't install when running Windows 7. Im currently tryin to solve the following problem on my cousins pc: He want win 7, but when I tried to install it for him, it goes wrong. What happens is that the install says that it makes the final configurations, and then it skips right to a black screen with a white blinking underscore. It never gets further than that. When restarting, win 7 install can't get done, because of some error. I looked it up, and it all seems to have something to do with the default microsoft win 7 drivers for the nvidia graphics-card. The one win 7 installs simply don't work, and the entire win 7 installation cannot complete because of this. They way to replace the drivers is to restart, press f8 to start in safe mode. When it's done, an error appears claiming that safe mode cannot be used. When this prompt appears, I can press SHIFT+F10 to open a command prompt. There I write compmgmt.msc to start the device manager. And there I can replace the driver with some working ones from nvidia. My problem now is that I have downloaded alot of versions from nividia for the GeForce 9800 GX2 for win 7 64-bit. I run the setupfile, to extract the drivers to a usbdrive. I then access the usb drive to replace the driver, following the method described above. But windows 7 just keep claiming that no proper driver is located in the folder. So now I have come down to this: Either the nvidia driver is not uninstalled properly for manual install, when I just double-clicked the downloaded file, and transferred the content to the usb-drive. OR I havent found the right driver yet. Any suggestions?
