I have a computer running Windows Vista Home Premium Edition, 32 bit. Not long after downloading the latest drivers for my graphics card, (nVidia GeForce 9500 GT,) my poor computer started having major start up problems. When I turn it on, it beeps, the lights come on, the fan comes on, then it shuts down. A few seconds later it starts again and boots, but to a black screen with nothing but the mouse arrow visible. After a few tries it will boot up, but of course because it didn't shut down properly because I had to force it by holding the power button, I have to do it in safe mode, then reboot again. It will then start up as normal. I'm afraid to shut it down now as I may not be able to get her going again. I can't even risk putting it in sleep mode, because when I "wake it up" I get that black screen again and have to pray it works as I start the whole sequence all over again.
I mention the downloading of the drivers for the graphics card because I had a similar issue a few years ago and it turned out the graphics card was dead. I replaced it with my current one and all was fine. I have looked up this problem and graphics card issues have been mentioned on several sites I looked at. I was thinking that if I were to replace the new drivers with the drivers I replaced in the first place that that may work to fix the problem. My computer has been on constantly due to my fear of shutting it down and not being able to start her up again. Any help would be appreciated.
