Stop codes
From NoovexOS, the free NoovexOS encyclopedia
A stop code is an identifier displayed by NoovexOS when the kernel encounters an unrecoverable fault and halts the system. Each code names the subsystem that failed and points to a recommended recovery action.
A reference guide for NoovexOS blue-screen stop codes. Match the code on your screen to what it means and what to do next.
Reference table
| Stop code | What it means | What to do |
|---|---|---|
NXPAGE_FAULT_IN_NONPAGED_AREAPage fault | The kernel tried to read or write memory that doesn't exist or is marked non-paged. | Remove recently installed hardware or drivers, then run a memory test. |
NXIRQL_NOT_LESS_OR_EQUALDriver IRQL issue | A kernel-mode driver accessed pageable memory at a high IRQL. | Update or roll back the driver that was active when the crash occurred. |
NXCRITICAL_PROCESS_DIEDCritical process died | A process required by the OS terminated unexpectedly. | Boot from recovery media and run /fsck to check the Atlas filesystem. |
NXPANIC_STACK_SWITCHStack switch | The kernel switched to an invalid stack while handling an exception. | Disable recent kernel patches and check for stack overflow in loaded modules. |
NXUNEXPECTED_KERNEL_MODE_TRAPKernel trap | The CPU generated a trap the kernel was not prepared to handle. | Check for CPU overheating, overclocking, or incompatible virtualization settings. |
NXXATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORYNo-execute memory | Code tried to run from memory marked as non-executable. | Enable NX/XD in firmware and update any custom bootloader. |
NXMACHINE_CHECK_EXCEPTIONHardware failure | The CPU reported a hardware-level error. | Test RAM, check CPU voltage/temperature, and verify cooling. |
NXWHEA_UNCORRECTABLE_ERRORUncorrectable hardware error | A fatal hardware error could not be recovered by the platform. | Run full hardware diagnostics and replace failing components. |
Notes
If a stop code repeats after these steps, capture the minidump and reach out on Discord or GitHub with your hardware or VM details.
