Hello and welcome to Bleepingcomputer.
Have you tried opening the compartment where your RAM is located, removing it, then re-seating it in the slot again?
Here is a link to windows stop errors http://www.aumha.org/a/stop.php
Please scroll down to "Page file in non-paged area" for an explanation.
Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems.
If re-seating your memory does not resolve this issue, you may have a defective RAM module.
Running memtest with at least 7 passes may find the module at fault, if you have more than one RAM module, try testing each one individually.
