Hi. I got win 7 x64 and nvidia gtx 480. From couple days I got problem with my card. One day my computer didnt wanted to start/ I had turn it on, went out, after 15 minutes I came back and I saw that it is rebooting all the time. I turn it on in safe mode and check with bsod view. Those are the problems that appears: nvlddmkm.sys dxgkrnl.sys dxgmms1.sys I tried many metods that I found on the internet but nothing works. After I remove all drivers, clean registry, etc, sometimes computer boots normal (in low resolution) and after that automaticly install vga driver. After that bsod again. If I am lucky I am able to install nvidia drivers (335.23), but after reboot I also get bsod. What can I do to fix it?
