i got this very recently after a random amount of time when i was just browsing. I have microsoft antispyware running which blocks most viruss and worms and stuff and the warning box popped up and i said remove or block depending on the type of infraction. After a few seconds i hit the BLUE SCREEN... then i tried restarting my copmuter and it worked fine and it booted normally and i had access to teh desktop for maybe a minute then everything went blue again. Then i went into safe mode and ran microsoft anispyware in a full deep scan and deleted all it found. I also ran a program called Bug Doctor to fix registry errors and stuff and catch additional spyware. after doing that i could no longer boot normally... on the xp loading screen with that little progress bar going back and forth, that screen came, then the blue one... i have written down the error code or w/e if that helps... i did some research and some people were saying it oculd be sp2? i know computers kinda well but im stumped on this... HELP PLEASE! ***STOP 0x00000050 (0xF9680A34, 0x00000001, 0xFF6FBB48, 0x00000000) again it displayed "PAGE_FAULT_IN_NON_PAGED_AREA" Thanks for any help!
