irql error

About this tag
The IRQL error, commonly seen as IRQL_NOT_LESS_OR_EQUAL or IRQL_UNEXPECTED_VALUE, is a Windows stop code that typically appears during a Blue Screen of Death (BSOD). On WindowsForum.com, users report this error occurring after Windows 10 upgrades, during gaming (e.g., alt+tabbing), on cold boots, or when connecting to networks. Common culprits include faulty drivers such as network adapter drivers (e.g., Killer 1535, Native WiFi Miniport Driver) or system files like ntoskrnl.exe. Troubleshooting steps discussed include analyzing crash dumps with tools like WhoCrashed or BlueScreenView, updating drivers, and performing clean Windows installations. The error affects various Windows versions, including Windows 7 and Windows 10.
