Page_fault_in_nonpaged_area errors have been around since Windows XP if not longer. They refer to Windows or a windows application trying to access a part of physical memory that is invalid. Either it is in use by another app or is reserved for something else. Windows somehow cannot cope with it and will generate this error and a Blue Screen of Death.
If you’re lucky, the error syntax will also tell you what caused the issue. For example, ‘Page_fault_in_nonpaged_area (ati.sys)’. The .sys file referred to in that error is the application that was trying to access memory it shouldn’t.
The error can be caused by hardware or software and will not typically happen out of the blue. It will most often occur just after a RAM or graphics card change, a Windows core or app update or when you have installed something new. With that in mind, the first troubleshooting you should do is to roll back whatever change you made. Remove the RAM, disable the service of the app you updated, uninstall it or roll back to a previous version. Only once you have done that should you move on.
