Hello! Having a problem with the GeForce 9800 GT, precisely Windows 7/8 64-bit won't recognize it. Previously I was using Windows XP Pro 32-bit and it worked fine. At the moment I'm using Windows 7 32-bit and no problems. I have tried installing the latest drivers for Windows 7 64-bit, but nothing seems to fix the problem. Tried multiple times installing and uninstalling drivers as well as Windows, doing clean installs etc. My processor is AMD Phenom 8650 Tripe-Core 2.3 GHz, so it support 64-bit Windows. Also I have 4GB of RAM. I have read numerous threads about similar problems but the solution hasn't been clear. It can't be video card's fault, because it runs fine with 32-bit Windows(and GeForce 9800 GT supports 64-bit). When checking under device manager on 64-bit W7 I get the code 43 for the video card(Windows has stopped this device because it has reported problems). Also if I try to open NVIDIA Control Panel I get and error saying "You are not currently using a display attached to and NVIDIA GPU" but I am, because my monitor is functioning. Thank you in advance !
