I have a nVidia GTX 650 that works (displays video output) before installing the driver, albeit with limited resolutions and no Aero Glass theme effects etc.
When I install the driver, there is no video output coming from any of the card's connections (two DVI, one HDMI and one VGA).
I've done a 'clean' install of the latest nVidia driver each time I've tried this card with no other graphics cards installed in the machine.
I am running Windows 7 Ultimate 64bit Service Pack 1.
I have a nVidia 8800 GT which I have been using before getting the 650 (the 8800 GT works fine) and when I install it alongside the GTX 650 and use its outputs I am able to get a picture on the display.
I checked the nVidia control panel's system information and the GTX 650 is detected and all of its information is shown correctly alongside the info for the 8800 GT.
Does anyone know if I can do anything to salvage this 650 or is it a lost cause?
Would updating the BIOS solve any issue that might cause this behaviour?
I just plugged an HDMI cable into the 650 while the computer was running and displaying from the 8800 GT, and it Blue Screened with the message: "Attempt to reset display driver and recover from timeout failed".
