After installing SP2 on Win XP, I am experiencing a strange problem of getting a blue screen with an error message Bad Pool Header. This happens when I try to edit or save any images from Microsoft Digital image pgm. It was working fine before SP2. It works just fine in safe mode. Any suggestions???? :confused:

Well, try this previous thread:

I don't know if it is USB/driver-related or hardware.
