I'm running Windows XP Media Center SP2 and every time I turn the computer on windows will go through all its processes until the desktop appears. Then as it plays the standard windows chime it gets stuck on the last chime for half a second and automatically restarts. I am able to start the PC by going into safe mode and resetting to the day before this problem started. However this has happened before. I had it checked out and tested at a PC shop and they told me all hardware checks tested fine. They couldn't find any viruses or any spyware that would cause this issue and advised me to reinstall media center. I then requested they do the reinstall which they kindly did. Now 3 weeks later I am faced with the same issue... Does anyone know of this problem? Restarting in safe mode and resetting the day only works for a while. Should I install a different copy of media center? Thank you for any assistance or adivce you can provide me.
