and, as you said, it only occurred with one user profile. I believe it also only happened with certain programs running such as media player. Memtest86 turned up no problems but the laptop this was happening on was marginal in RAM size. I increased the amount of RAM and the problem went away. I don't have a clue why but that worked for me.
I came across this crash and have been trying to solve the problem but with no luck. I'm getting the PAGE_FAULT_IN_NONPAGED_AREA blue screen of death. I am running WINDOWS XP. I have not installed any new hardware or software on my computer for many months. When I start my computer in safe mode and logon as the ADMINISTRATOR, works fine. When I logon as USER, it crashes. Then I created another account and named it USER2. When I start my computer in normal mode and logon with USERS, works fine. When I logon with USER, I continue to get the PAGE_FAULT_IN_NONPAGED_AREA blue screen of death. Please help, trying to fix this problem for 3 days. Any help would be appreciated.
