You can also try this registry key
go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvlddmkm
Create a new key dword 32bit key "EnableNonContiguousSVM", value:00000001
Restart your pc
This will make the error occur less frequently
You can also try driver 182.50 which is more stable than those 190.xx drivers

You should never really go to those sites there drivers are always out off date you are better off going to the chipset website.
