After loading Norton Internet Security, when the system reboots I get the Unexpected Kernel Mode Trap (STOP 0x0000007F) and then the system perpetually reboots itself. After lots of experimentation, here is how I resolved it (this is a combination of three individual fixes I found): 1. Removed IRPStackSize registry entry.

Add KStackMinFree registry entry. Info: http://service1.symantec.com/SUPPORT/ent-security.nsf/docid/2002071208532048?Open&src=w - I used the AnitVirus 8.x solution 3. Updated video drivers through Windows Update service. I did all this through safe mode w/ network support - couldn't get in any other way. Dan Freeman Breezeway Productions, Inc.
