List four critical questions that are often helpful to break out of a stalled troubleshooting situation.

What will be an ideal response?

Any four of the following:
1. Has the problem system, component, or feature ever worked?
2. Have you ever had this problem before? When?
3. Is the problem repeatable (can it be replicated)?
4. What were you doing on your PC just before you first noticed the problem?
5. Have you made any recent hardware or software changes to your system?
