When Things Go Wrong
Dealing with errors, blue screens, system crashes, and non-responsive computers can be very frustrating. When your computer acts up, Windows often leaves clues about what went wrong — you just need to know where to look.
Enter the Windows Event Viewer, one of the most useful diagnostic tools built right into Windows.
What Is Event Viewer?
Event Viewer is a Windows utility that logs almost everything that happens on your system. Application installs, system errors, security events, driver failures — it is all recorded here with timestamps and error codes.
How To Open It
Press Windows Key + R, type eventvwr.msc, and hit Enter. Or just search for "Event Viewer" in the Start menu.
What To Look For
Once open, the two most useful sections are:
- Windows Logs > System — This is where hardware and driver-related errors appear. If you are getting blue screens, the culprit is usually in here.
- Windows Logs > Application — Software crashes and application errors show up here.
Look for entries marked with a red Error or yellow Warning icon. The date and time column will tell you exactly when the problem occurred, which helps narrow down the cause — especially if it coincides with a recent update or software install.
A Pro Tip
When you double-click an error, the bottom pane shows details. The "Event ID" number is your best friend. Google that number along with "Windows 10" or "Windows 11" and you will often find a forum thread or Microsoft support article with the exact fix.
Event Viewer can seem overwhelming at first because there are so many entries, but do not let that discourage you. Most of the "Information" entries are just routine system activity. Focus on the errors and warnings, and you will be surprised how much you can learn about what your computer is doing.
If you are not sure what a particular error means, give us a call. We read Event Viewer logs every day — it is usually the first place we look when diagnosing a problem.
