Page fault in non paged area
My pc just restarted on its own. And after that there is a error on the scree. The error is associated with Page fault in non paged area. I am not able to understand why the error appeared on the screen. I tried system restore here but nothing worked. I thought system restore would be enough better to fix the problem I am facing. I am looking for some help here to fix the problem. Can anyone guide me how to get rid of the problem. Thanks.
Re: Page fault in non paged area
I don't have that file as no Norton software has been installed on this machine since I installed WinXP Pro 64 on it. I searched anyway, but no file.
I have been getting the "win32k.sys Page Fault in Non-Paged Area" crash since I upgraded the two monitors from 20" 1600x1200 to 24" 1920x1200 and installed Ultramon. I did check and find that my pagefile was way too small, and increased it to about 1.5 times my 8 GB of memory. No time to tell yet whether that will make a difference.
Next I plan to uninstall Ultramon.
After that I don't know. A page fault is not a fault in the conventional sense. It is operating system terminology for a signal from the CPU chip to the operating system that the currently executing process needs a memory page that is not presently in memory and has to be paged, or swapped in. If a page fault occurs in or for non-paged memory, that indicates a bug, either in the OS or in the application where the fault occurred. Any process can have non-paged memory, protected paged memory, and unprotected or writeable paged memory. The fact that the program identified in the BSoD is win32k.sys suggests that this may be a Microsoft bug. Win32k.sys is probably involved in running 32-bit apps in my 64-bit XP Pro OS. But I suppose it could also be indicative of a problem in one of those 32-bit apps.
It's just disconcerting that this occurred after upgrading the res on the two monitors. The only other change made to the system was installing the trial version of Ultramon, a utility for working with multiple monitors. Ultramon itself has not crashed afaik.
Oh yes, one more thing: I have ECC memory. That means Error Correcting memory. I really don't think this is being caused by the memory.
Re: Page fault in non paged area
There is one more application which cause the same issue. It is called as
Ultramon. You have to ensure that you must remove it. System restore can help you here only if there is a problem on the software level. Or else there is no option available to fix the issue. You have to check the ram. Bluescreen is also commonly caused due to memory faults. It is necessary that you must replace the sticks and then test the same back.
