I'm going to devote some time to getting a recent driver installed.
After the 270.61 drivers, nVidia changed from a windows installer to their own custom installer, and there are many who can't install them on their machines - including me.
I'm curious which drivers are stable.
BTW - I ask because it really does take some time to find a driver that is stable - and how to set up the nVidia control panel properly (which affects stability).
Just because it's a WHQL driver doesn't mean that it's stable. Many introduce memory leaks and other issues during their quest to get high benchmarks from video games - resulting in blue screens of death.
This quest for a stable driver is made a bit more difficult as one of the main sources of feedback, the nVidia forums, have been completely down since July 12, as they got hacked.
BTW - if anyone else is having issues, this guide on the EVGA forum is helpful. It outlines some changes nVidia made that make it impossible to install PhysX in SafeMode, and other "gotcha's" that can end up corrupting everything.
It definitely has good advice on what not to do during an install.
I'll post my routine for an install:
1. add/remove - un-install nVidia physX, then un-install nVidia driver
2. reboot into safe mode
3. In DriverSweeper, clean all nVidia and PhysX (but not nVidia chipset)
4. Delete c:\program files\nVidia corporation, also for x86
5. reboot and wait, the default vga driver should install itself
6. install nVidia driver
select CUSTOM option
CHECK 'perform clean installation'
Un-check everything else except 'graphic driver' and PhysX
