I recently found that that i had my graphic card installed on the wrong PCIe. Instead of using the 16x one (for Express 3.0) i was using the 8x one. So i just unplugged my graphic card from the 8x and installed it at 16x, my computer powered on, got into windows, it asked to install again the drivers of the graphic card and after all has been done, doing a restart i noticed that at startup it takes much more time than usual.
I unistalled the drivers of the GPU, reboot, installed them again, reboot and still startup is slower than it was.
Am i missing something? Did the change made some damage to the windows?
I am using Windows 7 64bit, Gigabyte Z77m-D3H and Nvidia GTX 660.
