Windows 10 generic errors

In the blue error screens on Windows 10, generic error codes may also appear, not necessarily related to the installation or update of Windows 10, accompanied by a string that is difficult to identify for a novice user. For this reason, we advise you to prepare the BlueScreenView tool and compare the error message with one of those collected below.

  • DRIVER_IRQL_NOT_LESS_OR_EQUAL: This error is generated when a faulty driver or driver not updated to the latest version is started. If it happens sporadically, it is always advisable to keep the drivers updated on the computer as seen in the guide Update the drivers of a Windows pc automatically; if it completely prevents the computer from starting, it is worthwhile boot into a known good configuration or boot in safe mode and uninstalls the latest installed or updated driver.
  • PAGE_FAULT_IN_NONPAGED_AREA: This error occurs when a new hardware component is added or if one of the components is damaged (especially RAM). To learn more we can read our guide Check PC RAM test with Windows memory diagnostics.
