310.07 is out of date. Update to 352.86 and see if you still have the issue.

I spoke too soon.  The problem re-occurred.   I uninstalled 327.xx and installed your recommended driver above.
Problem still occurs.   The corrupted screen fixes itself after about 1/2 a second.
 
This is in Windows XP.  Anybody else see this?
As I mentioned earlier, only happens when you scroll the yahoo homepage in Firefox.
Repeating the same test in IE8, it works fine.

Unfortunately, temporarily disabling Flash did not help.
 
I uninstalled the 352.xx driver and reverted to 327.xx.
 
One interesting thing, the 352 driver would not uninstall properly; I had to abandon the uninstall and
used system restore to revert to a time before 352 was installed.
When I clicked on the Nvidia graphics driver in add/remove programs, the green Nvidia window that normally
appears where you can either confirm or cancel the uninstall was only partially painted on the screen.
Opening task manager showed an associated rundll32 (it started up when the the uninstall was initiated) was using all the CPU.
After the system restore (successful) was complete, reinstalled 327.xx and everything back to normal -
except the original problem.
 
This is why I don't like using non-WHQL drivers.  I don't know what would have happened if I had tried to
install 327 on top of 352; I didn't try it.
 
I've had the EVGA 610 for less that a year and this device has been fine except for this one glitch,
whose cause (s far) is undetermined.

Maybe update the drivers and web browser?
