A problem appeared ~ 11 nov; after logon, but before everything has loaded I get a BSoD (Win XP, sp3). It is STOP: driver_IRQL_NOT_LESS_OR_EQUAL with bdselfpr.sys listed. By trial and error I found that the problem disappears if I remove SD card before boot. I ran BD 2010 repair tool recommended by BD chat but problem seems back. I've seen some "sandbox" stuff on the forum linked to bdselfpr.sys but I don' t have that (and don't know what it is). Help?!
