Leave a Reply Cancel reply Your email address will not be published. Auslogics Blog. A driver tried to access an address that is pageable or that is completely invalid while the IRQL was too high.
If the first parameter has the same value as the fourth parameter, and the third parameter indicates an execute operation, this bug check was likely caused by a driver that was trying to execute code when the code itself was paged out. Possible causes for the page fault include the following:. The function was marked as pageable and was running at an elevated IRQL which includes obtaining a lock.
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. If you do not have a Windows 7 disk you can borrow a friends as they are not copy protected.
Also you can make a repair disk on another computer. Retry Startup Repair after Chkdsk. Memory tests do not catch all errors such as mismatched memory possible even for sticks that appear to be identical and when faster memory is placed in system behind slower memory. So it is best to also swap sticks in and out to check for those even if all memory tests fail to show a problem. Was this reply helpful? Yes No. Sorry this didn't help.
Thanks for your feedback. I do not have an F8 option for repairing the computer at start up, just F2 and F Any ideas? In the debugger, run the! For example:. In the majority of cases of this type of bug check, the issue is not the IRQL level, but rather the memory that is being accessed. Because this bug check is usually caused by drivers that have used improper memory addresses, use parameters 1, 3, and 4 to investigate further.
Use ln list nearest symbols with parameter 4 to see the name of the function that was called. Also examine the! Use the display memory commands to examine the memory referenced in command in parameter 1. Use the u , ub , uu unassemble commands to look at the code in the address which referenced the memory in parameter 4. Use the command lm t n to list modules that are loaded in the memory. 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 identifies errors in the execution of driver code, it proactively creates an exception to allow that part of the driver code to be further scrutinized. To start Driver Verifier Manager, type verifier at a command prompt. You can configure which drivers to verify. The code that verifies drivers adds overhead as it runs, so try to verify the smallest number of drivers possible.
