Page fault in non paged area

Page fault in non paged area:

 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 (e.g., incorrect SCSI termination or a flawed PCI card).

" A page fault is a signal from the CPU to the OS to let the OS know that a memory page presently not paged in must be paged in for the current process to continue. In principle it has nothing to do with memory problems”.

*Solution:

Start system in Safe Mode,

*Check the hard drive for bad sectors by running chkdsk /f /r

*Use msconfig.exe to disable what startup programs it lists. It doesn't list all startup locations but this would be a start. Then reboot into normal mode to see if the problem went away or not.
Check the System log of Event Viewer for Error Reports.

Are there any yellow question marks in Device Manager?

 Right click onthe My Computer icon on your Desktop and select Properties, Hardware,Device Manager. If yes what is the Device Error code?

Try Start, Run, type "sigverif.exe" without quotes and hit OK. What drivers are listed as unsigned? Disregard those which are not checked.
