I recently upgraded to Windows 7 Professional 64-bit. Everything was working fine and dandy until one day I turned off my computer. I have a dual monitor setup. One monitor was connected to the integrated graphics card on the motherboard, while the other monitor was connected to the Nvidia Geforce 8600GT.
When I turned the computer on the next day the monitor connected to the 8600GT stayed in a black screen. I discovered the Device Manager stopped detecting the graphics card altogether as well. However, when I hit the windows+ P button to extend and go into screen resolution it shows 2 monitors. However, the one connected to the 8600GT says "Another Display Not Detected" and the resolution is grayed out. When I move my mouse over, the mouse goes onto the other screen, even though it does not detect the graphics card and the monitor is black!
I have tried and searched EVERYTHING. I have found MANY other people with the same problem and no solution. I switched monitors to make sure they both worked. I have gone into the BIOS and switched it to load the PCI Express graphics card instead of the onboard g-card (there is no option to disable the onboard g-card in BIOS). I went into the Nvidia Management options to make sure it was set to allow dual displays. I have installed older drivers
, tried compatibility with Vista, unplugged and replugged the graphics card.
Is there anyone out there who has actually solved this problem? Does anyone have any unique ideas?
