Your PC crashed with a blue screen, and you want to find out why. Guides tell you to look in C:\Windows\Minidump for a small file that records what happened, but the folder is empty or does not exist. When Windows 10 minidump files not created leaves you without clues, troubleshooting repeated slot88 crashes becomes guesswork.

A minidump is a small snapshot Windows writes during a crash. It records which driver or process was running when the error happened, and tools such as WinDbg or BlueScreenView can read it.

To write that file, Windows needs dump settings turned on, a paging file on the system drive, and enough free space. If any of these is missing, the crash happens but nothing is saved.

Cleanup tools that delete “unnecessary” files can also remove dumps soon after they are created.

What Usually Triggers It

Minidumps are missing for these reasons:

• “Write debugging information” is set to None.
• The paging file was disabled or moved off the C: drive.
• The system drive is almost full.
• A cleanup program deletes dump files automatically.

A sudden power loss or a hardware freeze without a blue screen also leaves no dump, because Windows never gets a chance to write one.

First Steps to Try

Turn dump creation on.

1. Press Windows + R, type sysdm.cpl, and press Enter.
2. Open the Advanced tab and select Settings under Startup and Recovery.
3. Under “Write debugging information,” choose Small memory dump (256 KB).
4. Make sure the Small dump directory says %SystemRoot%\Minidump.
5. Select OK and restart the PC.

Untick “Automatically restart” in the same window if you want time to read the blue screen’s stop code.

If the Problem Continues

Check the paging file and space.

1. In System Properties, open Advanced > Performance Settings > Advanced > Change.
2. Make sure the C: drive has a paging file, ideally “System managed size.”
3. Free at least several gigabytes on C: with Disk Cleanup.
4. Exclude C:\Windows\Minidump from any third-party cleanup tool.
5. Run sfc /scannow to repair system files that handle crash reporting.

After the next crash, check the Minidump folder and the Event Viewer System log for event 1001 from BugCheck.

If the Minidump folder is still empty after a crash, check C:\Windows for a file called MEMORY.DMP. Some settings write one large dump there instead of small files in the Minidump folder.

Protect Your Data First

Frequent blue screens can damage open files, so back up important data before experimenting. Keep the paging file enabled, since many programs depend on it.

The Bottom Line

Missing minidumps usually mean dump settings, the paging file, or disk space need attention. Turn on small memory dumps, keep a paging file on C:, and protect the folder from cleanup tools.
