Toshiba L500 Blue Screen crashes - Windows 7

Question

I have a Toshiba L500-1XJ, part no. PSLS0E-07D01DEN which crashes almost immediately on loading Windows 7.
As it belonged to my son, who is now using another machine, I have restored the machine to its original state and still the machine crashes.
The blue screen of death appears with the following message:
PROCESS HAS LOCKED PAGES
STOP: 0x00000076 (0x0000000000000000, 0xFFFFFA8004F4D060, 0x0000000000000033, 0x0000000000000000)
I am only able to access Windows in Safe mode, otherwise the machine crashes.
Microsoft Knowledge Base indicate the problem to be with a driver not cleaning up completely after an I/O operation and talks about editing the registry to find out.  I am hesitant about editing the registry as I have not done this before and am not not clear about adding parameters to the registry.
Microsoft Knowledge Base states -
=====>  Windows includes a registry value that you can use to save stack traces that enable you to identify the problem driver. 
Note Using DriverVerifier to enable the Pool Tracking option will result in the same behavior in Vista, 2008, Win7 and 2008 R2 as setting the registry value TrackLockedPages to 1. 
Use Registry Editor (Regedt32.exe) to view the following registry key: 
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
Add the following registry value, and then restart your computer:
Value Name: TrackLockedPages
Value Type: REG_DWORD
Value Data: 1
Radix: hexadecimal
After you make this change, Windows saves stack traces so that you can identify the problem driver. There is no other way to determine which driver is neglecting to clean up the I/O operations. After you enable this flag, if the driver commits the error again, you see the following error message:
STOP: 0x000000CB (0xY,0xY,0xY,0xY) DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS
Parameter 1 - The calling address in the driver that locked the pages
Parameter 2 - The caller of the calling address in the driver that locked the pages
Parameter 3 - A pointer to the MDL containing the locked pages
Parameter 4 - The problem driver's name (Unicode string)
The problem driver's name is listed on the blue "Stop" screen and is available for dumping again as the fourth parameter in the "Stop" data. 
After you identify and update or remove the problem driver, you should remove the TrackLockedPages value from the registry.
=====>
I have run regedit, but am not confident in what to do next.  Two folders are shown under Memory Management as well as a number of other files contained within the folder itself.  If I highlight Memory Management and click EDIT, NEW a number of options are presented - Key; String Value; Binary Value; DWORD (32-bit) Value; QWORD (64-bit) Value; Multi-String Value; Expandable String Value
How should I proceed?  Any help would be welcomed.
Thanks

Sorry, none of that helps me identify the hardware at fault.
