Ever since Microsoft kept bugging me to upgrade to Windows 2004, I have been having trouble with my system freezing.. To get the PC working again, I have to do a hard restart (hold the power button down until the PC shutoff, then restart the PC). I've gone to the error reporting section, but I can't see any errors that happen about the time the PC freezes. Other than Windows 2004 and of course the weekly update to Skype, no other software has been installed. If there a way to trouble shoot what is happening?
