Hi, I built my PC just over a year ago with help from this forum but now I have a problem with my graphics card. I have Windows 7 64bit and use an nVidia GTX460. A couple of days ago I turned my computer on and the resolution had gone back to the default one. When checking device manager my GPU is listed but it states "Windows has stopped this device because it has reported problems. (Code 43)". When trying to use the nVidia control panel it states I don't have an nVidia GPU attached. I have tried updating the drivers, uninstalling and re-installing the GPU, and system restore but nothing has worked so far. Is there anything else I can try or has my GPU had it? Thanks.
