Hi there, a desperate fellow first time posting looking for a solution to the same problem, heres my story:
I had WinVista 32 and it worked fine, it was new years and right past midnight I shut my computer off normally, when I wake up the other day I notice weird squares all over the initial Toshiba (I have a Satellite P105-S9337) and intel logos and boom....blackscreen listed above followed by a bluescreen which said dumping physical memory to disk at the bottom of the screen and FAULT_IN_NONPAGE_AREA at the top.
Was able to run it on Safe Mode, made a Backup and yesterday installed Win7 Ultimate x64, noticed the squares where still there, but i can boot it up normally (YAY half of the problem solved!!

). Then i noticed This was listed in Device Manager: Display Adapters--> Standard VGA Graphic Adapter(I got a Nvidia GeForce Go 7900GS as our chap above) This is also there with a ! sign: Mass Storage Device and Unknown Device under the Other Devices tab(though I'd like the focus on my video card problem for now please

)
So i ruled everything out and we got a pretty obvious driver problem, since then ive tried inumerous drivers (Given the one the Nvidia site found for me on the download drivers page is not even supported by my video card and it still showed up there as a driver for the 7900GS

).
Though Ive read posts here from people who got the same Video Card saying Win7 runs like a charm since a clean install.
Notes: This Started with the OS as WinVista 32.
I ran a clean Win7 Ultimate 64 Install.
Windows Update has a go at a Nvidia GeForce Go7900GS Driver update, right after that, I return to the blackscreen issue and when I'm able to boot it again it reverts changes
Thank you all for your help!
