Hi Wendy,
It looks like a Windows error, rather than an ArchiCAD error. It would also be useful to post an enlarged cropped image so people can actually read the error message, as it is virtually unreadable due to image compression currently!
You could also try pasting the error codes into google. It may bring up some suggestions.
edit - I was curious and put 'windows - no disk' into google which came up with a few suggestion, the most common one seemed to be connected with drive names - specifically not having the main drive called 'C' drive or the existence of a removable drive named 'C'. There are also suggestions of virus problems, and various windows updates causing it, so check your machine is fully updated and virus/malware-free also.
Hope that gives you something to start with. Your IT support person may be able to help further! Good luck!
