For the last couple of weeks I have been having serious trouble with my O/S XP pro ,was closing all programs after it went into screen saver mode ,then it comes up with an error message " There has been a serious error to the System ,it then asks me to send an error report which then freezes the PC , when repairing XP from the CD I received an error message" msi DLL file is missing surely it should be on the CD? well I have now removed most of my hardware ,it seems the problem is caused by the Driver for my printer Canon 6600D ,all seems well at the moment ,so heres hoping its o.k. any of you bright sparks any experience of this sort of thing?........Jim
