I just installed windows 7 on my computer. I have an Nvidia GeForce GTX 760M graphics card. I have installed drivers for my graphics card. My driver shows up in device manager with no yellow warning signs, but when I run dxdiag nothing shows up. I have checked the Nvidia website and confirmed that the driver I have installed is the latest recommended driver for me, but the website also says I have no driver installed, even though it shows up in device manager. The only other anomaly that may contribute to this problem is that there is a warning in my device manager next to a pci driver, but I have run Windows Update, and it can't find an update for it. Please help me fix this. P.S. I have tried uninstalling the drivers and reinstalling them several times.
