TECRA S5 Nvidia Quadro NVS130M - Sudden BSOD - Win 7 Pro 32-Bit

Question

Having moved from Vista to Windows 7, everything was working fine until two days ago, when suddenly my Laptop stopped working. I was forced to hard reboot it, and then all hell broke loose.
The problem is as follows:
Part Number info: PTS53E-00S009EP - Toshiba Tecra S5 - 2GB Ram Intel Core 2 Duo T7300 2.0 Ghz - Nivdia Quadro NVS130M
Windows 7 Professional 32-Bit begun to suddenly report and error code 43 for the graphic adapter (Nvidia Quadro NVS130M). I had the latest nvidia drivers, so I uninstalled the previous ones and rebooted the machine and installed the new ones. After reboot the Laptop crashed with a bluescreen.
I reverted to last known good configuration (default vga adapter drivers from windows which does not recognize the Nvidia Quadro NVS130M) and the Laptop booted up normally allowing me to enter Windows again.
I went back to the previous Nvidia drivers, and the same issue happened, bluescreen, revert to last known good configuration (default windows vga adapter driver).
I went back to the latest drivers for the Nvidia Quadro NVS130M found on the Toshiba downloads site, same situation as before.
I went all the way back to the oldest drivers on Toshiba Support Downloads site, and still the issue remains.
I have Windows 7 Professional 32-Bit since August and everything was working fine, it is fully updated, and have always used Nvidia's drivers both wit the factory default Vista and Windows 7.
I have not installed any windows updates recently, the last being early november 2011.
The only recent change, about 15 days ago, was that I finally found the drivers for the SD Card reader, they where for windows XP interestingly enough, but Windows 7 immediately recognized the SD Reader which it had not done until then. It couldnt even identify the sort of hardware it was.
I tried uninstalling the toshiba drivers for the SD Card Reader, but even then with that uninstalled, and the hardware disabled in the hardware management, when i try to use the factory drivers downloaded from Toshiba the bluescreen still happens.
One other symptom I've noticed is that if the bluescreen does not occurr ( when it does it specifically lists a file from the nvidia drivers as the cause), the computer will stay with a black screen and the fan will be running at extremely high speed, but there seems to be no HDD activity, as the HDD activity light on the Laptop does not light-up at all.
I have read there is an issue that may lead to the computer blocking or freezing unless the latest version of UPEK software is used. However it does not mention anything about a Bluescreen. Also since the Bluescreen error message specifically states the name of a Nvidia driver file, it wouldnt make much sense that he problem was the UPEK Fingerprinting software the one that was causing this.
It wouldnt make any sense at all since if I leave the default vga adaptor driver operating only and do not install any driver for the graphics board everything works fine, SD Reader, UPEK Figerprinting, etc....
I had everything working, including the fingerprinting software until exactly two days ago, so thats also puzzling me.
I have run Symantec's Endpoint Protection AV Software and the computer is completely clean, there are no virri, and nothign shows as abnormal.
I am now totally out of ideas and I cannot seem to find any information on this subject.
Your help highly appreciated and urgently needed, because if all else fails, I would be forced to rollback to Vista, something I really really really would not like to do, due to the usual hassle of reinstalling OS,Office, and Software for a grand total of over 50GB, and due to the fact that Vista is vastly inferior in so many aspects to Windows 7.
Thank you in advance for all your help and support.

Hi Jorge,
I also read about fingerprint driver which cause a freezing on Tecra series but as far as I know it was related to A11 and M11 series the S5 should not be affected but to be honest the described issue sounds more like a graphic chip issue
Possibly its not graphic driver related issue but graphic chip issue
But did you try to test the notebook with fresh preinstalled OS? Try this and use the OS which was preinstalled by Toshiba in such case you could check if its really a driver problem or chip issue
