OS: Win64 Vista Graphics Card: Nvidia Geforce 8800 GTX Hey, I accidentally installed two versions of the same latest drivers for my Nvidia Geforce 8800GTX card without restarting and now windows is unable to recognise my graphics card. I bought the 'drivercleaner' program and followed the instruction in the help section however to no avail. The process I went through was to first uninstall the nvidia display drivers as well as other related nvidia drivers and then rebooted my machine. After rebooting my machine there was still an exclamation mark in the Device Manager as an unknown device so I uninstalled that too. I then opened the driver cleaner program and set all the nvidia cleaning filters, including nvidia, nvidia control panel, nvidia HDMI Audio, nvidia Physx, nvidia Stereo and Nvidia WDM. After it finished scanning I then clicked clean for it to clean up all the files. I then rebooted my machine and when windows started up again it tried to locate the display drivers for the card but it said it failed because it was unable to recognise the device. Throughout this whole process my internet connection was off. I then went to nvidia website and downloaded the latest drivers for my card and then rebooted machine again however it still did not want to recognise the card or the drivers. I have tried this process 3 times already and am back to square one. I would appreciate it if an admin could tell me if what I am doing is correct or not and is there anything else I can do to get this working properly? Thanks.
