Getting.Page_Fault_In_ Nonpaged_Area?

Windows 7 . . . - x86 (32-bit) or x64 ?- x64 - the original installed OS on the system? - Yes - an OEM or full retail version? - Full Retail - What is the age of system (hardware)? - 1-2 Years - What is the age of OS installation - Did a clean install about a 6 months ago on a brand new sata HD.Im sure if you look at the dump logs youll see these error but Ill just tell you here anyway. These errors i believe where caused by my gpu driver being corrupted some how. Anyways i reinstalled a new drive and these are some of the errors I was getting.Page_Fault_In_ Nonpaged_Area, IRQL_Not_Less_Or_Equal, Bad_pool_header,NVLDDMKM.sys, NDIS.sys, NTFS.sys, Wiimfsf.sysAfter I reinstalled a new driver for my gpu from the NVIDA web site all seemd well. Then yesterday I received Memory_Management error..
