Crashes, No Sound, or Screen Glitches?

A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11If your Windows PC keeps crashing, there is no single replacement tool that identifies every cause. Start with the stop code and recent changes, then use Event Viewer to check what Windows recorded around the failure. If Windows saved a crash dump, WinDbg can inspect it—but interpreting the output takes experience. For suspected RAM problems, run Windows Memory Diagnostic. Get Help can handle certain specific issues, while recovery media is for a PC that will not start, not for finding the original cause.
Choose a tool based on what you need to find out
| Tool or route | What it can help with | What you need | Skill and risk |
|---|---|---|---|
| Event Viewer | Correlating Windows event records with the time of a crash | Access to the Windows event logs | Useful for ordinary troubleshooting; reviewing logs is observational, but an event near a crash is not proof of its cause |
| WinDbg | Inspecting a kernel crash dump | A saved dump file, commonly with a .dmp or .mdmp extension |
Advanced; debugger output needs interpretation |
| Windows Memory Diagnostic | Checking for possible RAM problems | A Windows system on which to run the test | A targeted check, not a diagnosis of every possible cause |
| Get Help | Running troubleshooters for supported, specific Windows issues | Access to the Get Help app and a listed issue category | Guided; it returns findings and suggested remedies, not crash-dump analysis |
| Windows Recovery Environment or recovery media | Repairing startup problems or reinstalling Windows when needed | Access to recovery options, or a USB recovery drive or installation media if required | Recovery rather than diagnosis; reinstalling from installation media removes everything from the device |
For a recurring blue screen, an unexpected restart, or a stop code, begin with the evidence already available on the PC. Microsoft Support says, “An unexpected restart might be caused by a hardware device, its driver, or software.” A stop code or named module can help narrow the investigation, but neither establishes the root cause on its own. The displayed stop-code screen can also vary by Windows version. See Microsoft’s blue-screen and stop-code guidance.

1. Record the crash before changing anything
Write down the stop code, any module name shown, the approximate time, and what changed shortly beforehand. Relevant changes include a driver update, newly connected hardware, or a recently installed application. This gives you details to compare with event records and helps distinguish a recurring pattern from a one-off failure.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Note whether the PC displayed a blue screen, restarted unexpectedly, or failed to start again.
- Record any error text exactly rather than assuming a familiar-looking code identifies a particular component.
- Keep track of recent changes, but treat timing as a clue—not proof that the change caused the crash.
2. Correlate the failure with Event Viewer
Event Viewer shows Windows event records, including their source, time, code, and message. To open it, search for Event Viewer from Start or press Win+R, enter eventvwr.msc, and press Enter. Review the Windows Logs > System entries around the time you recorded.

- Open Event Viewer using Start search or
eventvwr.msc. - Choose Windows Logs > System and locate records near the failure time.
- Read the event source and full message; note entries that coincide with the restart or blue screen.
- If you need to examine or share the timeline later, use Event Viewer’s filtering and save or export options.
A critical event that appears at the same time is a lead to compare with other evidence, not automatic proof of the cause. Microsoft describes Event Viewer and the eventvwr.msc launch method on its system tools page.
3. Use WinDbg if Windows saved a crash dump
WinDbg is Microsoft’s debugger for analyzing kernel dump files. It is the most relevant option here when you have a saved dump and the experience to interpret debugger output. Installing WinDbg alone does not diagnose every crash, and a dump’s findings still need to be considered alongside the timeline and other symptoms.

Windows Memory Diagnostic is a built-in check for suspected memory problems and is listed in Microsoft’s blue-screen troubleshooting guidance. After the test, check Event Viewer for its result. A memory check addresses RAM; it does not rule out other hardware, driver, or software causes.

5. Try reversible checks before recovery
If Windows still starts, Microsoft’s basic troubleshooting steps include removing recently added hardware, trying Safe Mode if restarts make normal access difficult, checking Device Manager for devices marked with an issue, ensuring there is enough free disk space, and installing Windows updates. These are checks to work through in light of what changed and what the error evidence shows—not a guarantee that a crash will be fixed.
- Disconnect recently added hardware and see whether the symptom changes.
- Use Safe Mode when you need to troubleshoot a PC that cannot remain stable during a normal start.
- Look in Device Manager for marked devices and review available Windows updates.
- Check that the system has adequate free disk space.
Do not casually disable drivers or change boot settings. Microsoft warns that misconfiguring System Configuration can make Windows unstable or prevent it from starting, and recommends backing up before making changes. Its system tools guidance includes this caution.

6. Use Get Help for a specific supported issue
Get Help offers troubleshooters for listed scenarios such as audio, Bluetooth, network, printer, compatibility, video, and Windows Update problems. Microsoft says the app provides findings and suggested remedies. It is a useful route when a crash appears tied to one of those issue areas, but it is not a general-purpose reader for kernel crash dumps. See Microsoft’s Get Help troubleshooting information.
Recommended Free Tools
Microsoft has published a plan to retire the Microsoft Support Diagnostic Tool (MSDT) and legacy inbox troubleshooters, redirecting some to Get Help and removing others. Its page describes an estimated 2023–2025 timeline and notes that exact Windows 11 applicability depends on release status. Because the transition is version-dependent, check the current Microsoft page and your Windows build rather than assuming every PC has identical troubleshooters or behavior.
7. Keep recovery separate from diagnosis
If the PC will not start, Windows Recovery Environment, a USB recovery drive, or Windows installation media may help you access recovery or reinstall Windows. These options address startup or restoration; they do not explain why the original crash happened. Microsoft’s Windows recovery options describe the available routes. Before using a USB recovery drive or installation media, protect important files and make sure you can access the recovery method you need. Reinstalling Windows from installation media removes everything from the device.
Protect diagnostic data when sharing it
Microsoft warns that optional diagnostic data may include memory state from a system or app crash and could unintentionally contain parts of a file that was in use. A dump or diagnostic file shared with a forum, repair shop, or support contact may therefore contain sensitive information. Consider what it could include and send it only to a recipient you trust. See Microsoft’s Windows diagnostic data information.
