IRQL_NOT_LESS_OR_EQUAL This Stop message indicates that a kernel-mode process or driver attempted to access a memory address to which it did not have permission to access.The most common cause of this error is an incorrect or corrupted pointer that references an incorrect location in memory.
SYS is a Windows system file or if it belongs to an application that you can trust. This is either a bad memory pointer or a pageability problem with the device driver code.If a kernel debugger is available, obtain a stack trace.The IRQL_NOT_LESS_OR_EQUAL bug check has a value of 0x0000000A.This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at an invalid address while at a raised interrupt request level (IRQL).driver is being loaded, or during Windows startup or shutdown.Keeping track of when and where your STOP error occurs is a critical piece of information in troubleshooting the problem. SYS blue screen errors can be caused by a variety of hardware, firmware, driver, or software issues. SYS errors can be caused by: Caution: We do not recommend downloading SYMEVENT. These sites distribute SYS files that are unapproved by the official SYMEVENT. This means that a driver has direct access to the internals of the operating system, hardware etc. The driver can be started or stopped from Services in the Control Panel or by other programs. A driver is a small software program that allows your computer to communicate with hardware or connected devices. These commands, may also be useful in gathering information about the failure: ! Bit 0: VALUES: 0: Read operation 1: Write operation Bit 3: (Only available on chipsets that support this level of reporting.) VALUES: 0: Not an execute operation 1: Execute operation Bit 0 and Bit 3 combined values: Bug check 0x A is usually caused by kernel mode device drivers using improper addresses.This bug check indicates that an attempt was made to access an invalid address while at a raised interrupt request level (IRQL).
