Just yesterday a strange thing happened to my computer. My computer was on but my monitor had gone into standby mode because it could not detect a signal. After turning it off and then on again it came back on but the resolution was not at what it should be (1680 x 1050 widescreen).
I'm running Vista, so I went into the display settings and discovered that the maximum resolution I could set was too small (cant remember what it was exactly) and made everything on my screen jumbo sized.
So I did a bit of googling and discovered that the video driver could be to blame, so I uninstalled my NVIDIA and re-started the computer and was able to put my resolution back to my normal 1680 x 1050. Problem now is I cant do much in the way of graphics / video which is really annoying. I need to have the video driver but I also want my normal resolution!! I have tried downloading the latest driver made for Vista from the NVIDIA site but this still does the same thing.
