G570 Crashes with BSOD on startup

Question

In Februrary, my trusty T61P Thinkpad failed with the well-known GPU failure while on a business trip in Melbourne, Australia.  The only option was a motherboard replacedment as $600-700 so I had to buy another laptop downunder and ended up with a cheap G570 to get me through for a few months.  It is now failing on startup. When it reaches the Win 7 desktop, I get a BSOD that reads: PAGE_FAULT_IN_NONPAGED_AREA
See this link for some details on the error and its causes: http://msdn.microsoft.com/en-us/library/windows/hardware/ff559023%28v=vs.85%29.aspx
I have tried every possible remedy.  I have run a chkdsk /f /r which thoroughly scanned the hard drive and reported no NTFS file system errors.  I have booted from a CD into memtest86+ and run the tests for several hours on the RAM.  It passed all tests and did not report any RAM errors.
I have booted into Advanced Options|Last known good configuration from the F8 menu and run a Windows repair which reports that it cannot fix the problem.
Based on the possible causes for this memory related error, my guess it that the CPU had a cache memory failure or video card RAM problem (I don't know if this model has dedicated video RAM).
The error occured when I tried to hook up an external monitor to the VGA port.  I have run projectors off this laptop with no problems several times.  The desktop locked up and when I rebooted, the page_fault error occured and has been with me ever since.
When I boot into Safe Mode, I get a totally black desktop and can do nothing but power off the computer and reboot
It boots fine and lets me login, but, when the desktop loads, its BSOD time.  Any ideas?

Hi Hoopster,
First of all - I'm sorry for Your T61p, it is a great machine indeed.
You can check detailed specification on this page or google Your product ID number - the one that starts with 59-. The BSOD You have (0x50, am I correct?) may indicate L2 cache issue, in this case try the Intel Processor Diagnostic Tool. If you have a discrete GPU try some third-party diagnostic tool like Video Card Stability Test.
You can also try downloading a bootable Linux distribution and trying to duplicate the issue by stressing the CPU and/or GPU.
