I did update the most current driver (10-25-10) I thought it was ram based since I was getting the page fault error as well, but since I switched the Ram I only get the NV4 error and only during game play, where I was getting the page fault and others randomly. I disabled my old sound card as well as I use a usb headset now. The exact code I get is
NV4_DISP.DLL address BD548549 base at BD012000 Datestamp 4cb9d749
STOP 0X0000007E (0xc0000005, 0XBD548549,0XAF909BD0, 0XAF9098CC)
I am running SP3, I had this same configuration before and before the recent crashes starting approx Dec 2 with an AVG file which I have removed. Could it be my graphics card itself? this is crazy
