Code reference and safe checks
Read the exact screen and operation before selecting a repair. This page does not run commands or collect files, keys or logs.
What this value means
This Device Manager error message indicates that the device requires a forced configuration.
Read this number in Device Manager > device Properties > Device status for the exact affected device.
| Code | 34 |
|---|---|
| Symbol | CM_PROB_NO_SOFTCONFIG |
| Windows family | Device Manager codes |
| Source level | Microsoft Device Manager code page |
Microsoft’s general resolution note says: Change the HW settings (by setting jumpers or running a vendor-supplied utility) and then use Device Manager's Resources tab to set the forced configuration. Match the exact device and manufacturer before acting.
Safe next steps
- For 34 (CM_PROB_NO_SOFTCONFIG), open Device Manager > the affected device > Properties and copy the full Device status message, not only the number.
- Check the exact device and PC maker’s official driver and diagnostic path. If a supported rollback is available after a recent change, record the old and new versions.
- A problem code does not prove the hardware is permanently damaged; stop if the device is physically unsafe.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
