I have Vista and I powered down one day and now when I try to boot up, it stays on the loading screen with the moving bar. It boots up in safe mode but not regular. I even tried reinstalling windows and cleaning the HD with a complete installation and it boots up the first time, but when I try tried to enable the ethernet card, it would stay on Enabling. I then powered off and it did the same would only stay on the loading unless I booted in safe mode. I don't know if it is a virus in the boot system or something. Please help I can't boot up windows in regular mode even after reinstalling windows. Thanks for your help.
