How Do I Fix IRQL_NOT_LESS_OR_EQUAL Error in Windows 8?
IRQL_NOT_LESS_OR_EQUAL error in Windows 8 is displayed as a dreaded Blue Screen of Death (BSOD). Just like other Blue Screen of Death errors, IRQL_NOT_LESS_OR_EQUAL errors arise from corrupt software installations, corrupt system files, incompatible or inappropriate device drivers and faulty hardware devices. IRQ are interrupt requests that are sent to the CPU via south and north bridges.
To fix this issue, administrator-level users can enable the advanced boot menu in Windows 8 and restart the computer in safe mode. After restarting in safe mode, admins can uninstall the problematic device driver or application. Problems can be narrowed down and detected by viewing the minidump file that is generated when a BSOD is displayed on the screen. To view the contents of a minidump file, we recommend an application called BlueScreenView, though you may wish to use another as preference dictates.
Note: BlueScreenView can be executed easily even when Windows 8 is running in safe mode.
As soon as the executable file of BlueScreenView application is initiated, it automatically detects and opens all the existing minidump files that the computer may have. Administrators can then view the contents of the most recent minidump file to find the problematic application or device driver, and can uninstall the program from the computer. In case a hardware device is found to be at the root of the issue, that device can be removed from the computer and replaced with the new one.
Another easier way of rectifying the IRQL_NOT_LESS_OR_EQUAL error in Windows 8 is by downloading and installing a powerful application named SlimCleaner. This application automatically detects the problematic software applications or device drivers. Using SlimCleaner is fairly straightforward, and the free version has a host of tools that will help you catch issues you might be having at the software level.
Your most likely route will be to manually uninstall the offending device driver or application, and for that you'll need to get into safe mode. To get there, you'll need to enable the legacy advanced boot menu.

Hi, The attached DMP file is of the DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1) bug check. This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high. Hello, every one out there. I was playing a game, nothing that was intense, and twice so far I received a IRQL_NOT_LESS_OR_EQUAL blue screen of death.

The DRIVER_IRQL_NOT_LESS_OR_EQUAL bug check has a value of 0x000000D1. This indicates that a kernel-mode driver attempted to access pageable memory while the process IRQL that was too high.
Important
This topic is for programmers. Cannon mg5220 driver. If you are a customer who has received a blue screen error code while using your computer, see Troubleshoot blue screen errors.
DRIVER_IRQL_NOT_LESS_OR_EQUAL Parameters
Parameter | Description |
---|---|
1 | Memory referenced. Radeon 5700 driver. |
2 | IRQL at time of reference. |
3 | 0: Read 2: Execute 8: Execute |
4 | Address that referenced memory. Use `ln' on this address to see the name of the function. |
Cause
Typically, a driver tried to access an address that is pageable (or that is completely invalid) while the IRQL was too high.
This can be caused by: Rtl8188etv driver.
- Dereferencing a bad pointer (such as a NULL or freed pointer) while executing at or above DISPATCH_LEVEL.
- Accessing pageable data at or above DISPATCH_LEVEL.
- Executing pageable code at or above DISPATCH_LEVEL.
If a driver responsible for the error can be identified, its name is printed on the blue screen and stored in memory at the location (PUNICODE_STRING) KiBugCheckDriver. You can use the debugger dx command to display this -
dx KiBugCheckDriver
.This bug check is usually caused by drivers that have used improper memory addresses.
Possible causes for the page fault include the following:
Epson Error Code 0x97
- The function was marked as pageable and was running at an elevated IRQL (which includes obtaining a lock).
- The function call was made to a function in another driver, and that driver was unloaded.
- The function was called by using a function pointer that was an invalid pointer.
Resolution
If the problem is caused by the driver that you are developing, make sure that the function that was executing at the time of the bug check is not marked as pageable or does not call any other inline functions that could be paged out.
The !analyze debug extension displays information about the bug check and can be helpful in determining the root cause.
If a trap frame is available in the dump file use the
.trap
command to set your context to the provided address.To start, examine the stack trace using the k, kb, kc, kd, kp, kP, kv (Display Stack Backtrace) command.
Use the
!IRQL
command to display information about the interrupt request level (IRQL) of a processor on the target computer before the debugger break.The majority of the time the issue is not the IRQL level, but rather the memory that is being accessed. Firefox version 24 download mac.
Because this bug check is usually caused by drivers that have used improper memory addresses, use parameters 1,3 and 4 to invesitgate further.
Use ln (List Nearest Symbols) with parameter 4 to see the name of the function that was called. Also examine the !analyze output to see if faulting code is identified.
Use !pool on the parameter 1 address to see whether it's paged pool. Use !address and the advanced !pte command to learn more about this area of memory.
Use the display memory commands to examine the memory referenced in command in parameter 1.
Use the Unassemble command to look at the code in the address which referenced the memory in parameter 4. How to download terrordrome on mac.
Use the
lm t n
to list modules that are loaded in the memory. Use !memusage and to examine the general state of the system memory. Disketch disc label software serial number.Driver Verifier
Driver Verifier is a tool that runs in real time to examine the behavior of drivers. For example, Driver Verifier checks the use of memory resources, such as memory pools. If it sees errors in the execution of driver code, it proactively creates an exception to allow that part of the driver code to be further scrutinized. The driver verifier manager is built into Windows and is available on all Windows PCs. To start the driver verifier manager, type Verifer at a command prompt. You can configure which drivers you would like to verify. The code that verifies drivers adds overhead as it runs, so try and verify the smallest number of drivers as possible. For more information, see Driver Verifier.

Remarks
Windows 8 Error Code Driver_irql_not_less_or_equal
If you are not equipped to use the Windows debugger to work on this problem, you can use some basic troubleshooting techniques.
- Check the System Log in Event Viewer for additional error messages that might help identify the device or driver that is causing this bug check.
- If a driver is identified in the bug check message, disable the driver or check with the manufacturer for driver updates.
- Confirm that any new hardware that is installed is compatible with the installed version of Windows. For example, you can get information about required hardware at Windows 10 Specifications.
- For additional general troubleshooting information, see Blue Screen Data.
