What do you do with the following error message on a blue screen? PAGE_FAULT_IN_NONPAGED_AREA 'Page fault in nonpaged area' is the error message for the 0x50 stop error on a Windows PC.
But what does that mean? At its most basic, the error means that your PC asked for a page of memory in order to continue, and the page was not available. Windows, as a result, was unable to continue the processes it was running, and crashed with what is commonly known as the Blue Screen of Death (BSOD). Below, we'll break down the different parts of this error message to help you understand what it means, and then discuss how to fix it. Your PC contains many different components that are used for storing data, these include - among others - the hard drive and random access memory (RAM).
One of the major differences between an hard drive and RAM is the duration of storage. RAM is the dynamic, short-term storage, that only remembers it's contents while the computer is on and running. This is opposed to permanent hard drive storage, which stores data while the computer is off. RAM is faster to read than hard drive storage, and contains the information required for the computer to process its current active task. When there is too much data to all be held in RAM, data that is not actively in use is stored temporarily in the page file, a location on the hard drive that the computer uses as additional RAM storage. Pages of memory are swapped between the physical RAM and the page file on the hard drive as required for a given task.
The Non-Paged area is an area of memory that contains data that is critical for the running of the system. This data is always required, so instead of swapping the data back and forth between the RAM and the page file, the data is kept constantly in RAM, in the non-paged area. Essentially this area is where data that should not be moved from RAM to the page file is stored. This error occurs when Windows attempts to access critical data from memory that was supposed to be stored in the Non-Paged area, but cannot find it. Because this area of memory is reserved for the Windows core, it is unlikely to be caused by an error in software code, and most likely to do with hardware. While it's possible that software (such as an antivirus product) may have accessed the non-paged area and in the process removed or edited the data windows was looking for, the mostly likely culprit is faulty RAM. It may also suggest a hardware problem with the level one or level two cache or corrupt sectors on the hard disk.
