Hi, I've been having an issue which is causing me to have to reinstall my video card driver after every reboot. I have another video card enabled on my system just so that I can restart my computer - typically if I use my new card (GeForce 9400GT), I get to the screen right before where I would enter my Windows user name and password and I get nothing but a blank screen - I know the PC is starting up because I can hear the startup sound. If I reboot it in safe mode, it starts up just fine. What I end up having to do in order to start up is unplug the cable connected to my new video card and wait until windows starts (with the incorrect resolution and graphics), change the resolution, disable the crappy video card, plug the cable connected to the good one into my monitor and hope for the best. Usually this goes pretty smoothly.
I tried this card/driver in my old PC and I don't have the problem on that computer, so I know the card and drivers are not the problem.
