I was watching Voyage To The Planet Of Prehistoric Women, when during a exciting part the machine rebooted. I looked up the error code for the time of shutdown and it gave me:6009 Microsoft ® Windows ® %1 %2 %3 %4. So I went to:http://www.microsoft.com/technet/support/ee/transform.aspx?ProdName=Windows+Operating+System&ProdVer=5.2&EvtID=6009&EvtSrc=EventLog&LCID=1033. It says I pressed shutdown, but I did not have the keyboard or mouse near me. This happened once a few months ago, but the computer has been running great otherwise. I have watched many DVDs [20] between the first and second time. winXPx64, biostar socket 775, 3 gb ram,ATI 3450, audigy, Enermax 450 Watt
