Is your pc or laptop compatible with vista. how much physical memory do you have (512 , 1024mb etc)? . Sometimes when i my vista ultimate pc when it starts up it takes sometime to actually run because the sidebar has a few gadgets on it which requires the internet. You have windows aero mode that could be bringing your system down if there isnt enough memory.
I just upgraded to Visa from XP and have a serious startup problem. When I startup into normal mode it takes 15 minutes to load and run. I spent 3 hours with Microsoft and nothing was found wrong. No driver conflicts or hardware issues. Running in full Areo mode. I spoke with the Video Card company and they have heard of the issue but could not fix the problem. It's not a video card issue. My system works fine in Safe Mode and starts quickly. Any suggestions or known file conflicts?
