I have windows vista basic. My problem is the loading screen before windows actualy starts. The bar at bottom with the little bars going through it. Sometimes it gets stuck there and wont go past that past.(the bar still keep soing) i left it like this for over a hour before incase was slow loading. I have to shut down. When i power off and restart, it says windows did not shut down properly and sugest to do a repair. I do this. But this is happening a lot more lately. Anyone know whats causing this?
