I just replaced the hard drive in my HP Pavillion dv6000. I managed to get in and running with Vista Home Premium installed. The only thing is it that Vista is running in a very graphics reduced way and restarts frequently without any prompt. The taskbar and side bar are grey along with all the windows that pop up. The hard drive I installed is a 500GB Seagate Momentus but when I look under my drives it only shows C: as being 24gb with only 3 being left after Vista installs. Any idea or help with this?
