Why is there a ‘page fault in nonpaged area’ error message when booting Windows?

Paul Synn September 14, 2011

Laptop fails to load normal Windows without being done in Safe Mode. Initial error code comes up or simply fails to load anything. Hard drive seems to not boot properly. Help!

    In my experience, these errors are usually caused by bad ram or a faulty hard disk sector (Commonly called a 'bad sector') - If you have other ram you can try, do that first (Even buying new ram isn't a bad idea as it is so cheap now) then check your hard disk for errors.

    Go into Safe mode, open 'Computer' right click the hard disk and choose 'properties', go to the 'Tools' tab, and click the 'Check Now' button in the 'Error Checking' section. Make sure the 'Automatically fix file system errors' is ticked.  It will tell you you need to reboot.

    Another option you should try is to go into your BIOS and Load Fail-Safe settings.  You can frequently get this error message when overclocking has been pushed too far.  In general terms, the memory timings are too short to properly store or retrieve data from RAM and the processor ends up with corrupted data when it needs it again.

    if you have different hard disk like SCSI and SATA you should detach one of them

    This is usually caused by an incompetent programmer. Basically the developer of the application attempted to allocate memory in a sector which didn't exist or was already in use. However if Windows OS caused this crash, it's most likely a hardware issue.

    Restart and as soon as your PC boots up (at the BIOS screen) you should have an option to edit what you boot from (F12 or Delete usually) and see if your BIOS provides a diagnostics utility. If it does you should be able to test your ram from there. 

    If you don't have a diagnostics utility, when booting into Windows tap F8. A menu will appear prompting you to chose what you would like to boot, select "Last Known Good Configuration". If this fails, you can restore your system from safe mode. 

    Sometimes restoring to a previous point may fail in safe mode. In this case open up a command prompt (still in safe mode) by going to start -> search: "cmd.exe" and press enter. A command prompt will appear, type "chkdsk /F". This will search your hard drive for bad sectors and attempt to repair them. It may require that your restart in order to do so. 
    What Is Page Fault in Nonpaged Area?

    You will have to be more specific about the error presented on screen. Next time your system bugchecks and you are presented with the BSoD please write down the following information in addition to the "page fault in nonpaged area":
    - the STOP code e.g. 0x00000000 (...)
    - associated files e.g. tcpip.sys (0xaa49d9de ...)

    For the STOP code the information before the brackets is enough, for associated files the first memory address within the brackets is required.

    It would also be good to know what you did, changed, installed, deinstalled or ran on your system before the error appeared for the first time.
    Without the STOP code and/or associated files the error message itself can relate to any and all sorts of problems e.g. defective RAM, Graphics, Sound or addon card, not correctly installed RAM, Graphics, Sound or addon ard (physically not properly in the socket), defective or wrong hardware driver, even overheat or defective installations of software can cause a page fault.
