Type command in the Start Menu search box and choose Command Prompt, type in
command prompt
chkdsk c: /r
then
sfc /scannow
The first checks the disk surface and file system and the second repairs
corrupted files. If Chkdsk doesn't find anything then it may be a driver.
You may want to run the memory check overnight just to be certain. Also
unplug what you can (USB keys etc) to see if that helps.

Bug Check 0x50: PAGE_FAULT_IN_NONPAGED_AREA
The PAGE_FAULT_IN_NONPAGED_AREA bug check has value 0x00000050. This signals
that invalid system memory has been referenced.
Parameters
The following parameters are displayed on the blue screen.
Parameter Description
1 Memory address referenced
2 0: Read
1: Write
3 Address that referenced memory (if known)
4 Reserved
If the guilty driver can be identified, its name is printed on the blue
screen and stored in PUNICODE_STRING parameter of KiBugCheckDriver.
Cause
Bug check 0x50 usually occurs after the installation of faulty hardware or
in the event of failure of installed hardware (usually related to defective
RAM, be it main memory, L2 RAM cache, or video RAM).
Another common cause is the installation of a bug-ridden system service.
Antivirus software can also trigger this error, as can a corrupted NTFS
volume.
Resolving the Problem
Resolving a faulty hardware problem: If hardware has been added to the
system recently, remove it to see if the error recurs. If existing hardware
has failed, remove or replace the faulty component. You should run hardware
diagnostics supplied by the system manufacturer. For details on these
procedures, see the owner's manual for your computer.
Resolving a bug-ridden system service problem: Disable the service and
confirm that this resolves the error. If so, contact the manufacturer of the
system service about a possible update. If the error occurs during system
startup, restart your computer, and press F8 at the character-mode menu that
displays the operating system choices. At the resulting Windows Advanced
Options menu, choose the Last Known Good Configuration option. This option
is most effective when only one driver or service is added at a time.
Resolving an antivirus software problem: Disable the program and confirm
that this resolves the error. If it does, contact the manufacturer of the
program about a possible update.
Resolving a corrupted NTFS volume problem: Run Chkdsk /f /r to detect and
repair disk errors. You must restart the system before the disk scan begins
on a system partition. If the hard disk is SCSI, check for problems between
the SCSI controller and the disk.
Finally, check the System Log in Event Viewer for additional error messages
that might help pinpoint the device or driver that is causing the error.
Disabling memory caching of the BIOS might also resolve it.
Comments
Typically, this address is in freed memory or is simply invalid.
