The "IRQL NOT LESS OR EQUAL" bug check (0x0000001A) typically indicates that Windows or a kernel-mode driver is trying to access paged memory at an invalid address while operating at a raised interrupt request level (IRQL). This can happen due to several reasons, including:
- Driver Issues: Outdated or incompatible drivers can cause this error. Ensure that all your drivers, especially for the graphics card and motherboard, are up to date.
- Hardware Issues: Faulty hardware, such as RAM or the motherboard, can lead to this BSOD. You might want to run hardware diagnostics to check for any issues.
- Memory Problems: Running the Windows Memory Diagnostics tool can help identify any memory-related issues.
- Overclocking: If your system is overclocked, reverting to default settings may help resolve the issue.
- System File Corruption: Corrupted system files can also lead to this BSOD. Running the System File Checker tool (
sfc /scannow) can help repair any corrupted files.
Since you mentioned that the issue persists even in Safe Mode, it suggests that the problem may be related to hardware or core system files rather than third-party drivers. If the problem continues, consider checking the minidump files for more specific errors related to the crash, which can provide insights into the exact cause.
