Here is a tutorial on running memtest86+ RAM - Test with Memtest86+
Do you have a wireless card installed?
The drivers for your motherboard are located here. Make sure that is your motherboard, but I believe that is the motherboard you listed in the first of this thread. Unless you have add on hardware, those are the only drivers you should need except your graphics card driver.
Download the 306.97 drivers from the Nvidia site.
I will post in a seperate post how to update Nvidia drivers for those having driver problems, if you like. But, the PhysX driver cannot be uninstalled in safe mode and the display drivers cannot be uninstalled from device manager nor rolled back from device manager any longer. That is why your latest driver install did not install the physX driver.
