Hello, still confused with those BSOD... as they came around every day on different PC's.. Still reading and have no idea, what to do: to return to waranty or try get out of mind? As I cannot remove any parts from my laptop (I think so..) to test it. So, now I have Vista on TOSHIBA laptop and usually get a 0x0000007F error. Two minidumps attached. Thanks. P.S. it now occurs ussually when I try to scan disk with AVAST... but I read this error is related with symantec.. maybe I should use those recomendations?
