I think you mean what we call the "blue screen of death" on Windows machines when they crash, so I would write this tech question like this:
I sent out an email to users who were getting the blue screen of death on their Windows machines. Some of the users that I contacted confirmed that they haven't encountered this screen in the past two weeks. The technical support team has put his ticket on hold. Should I ask them to close it or should I ask them to reassign the ticket to me so I can close it? Please advise.
