Happened to me few times, but i got the message BSOD, also while playing Crossfire, from time to time i have PC crashes BSOD again [Just for the records: when it comes about games this BSOD(blue screen of death) happens only in CF!]But maybe this is not worthy report for u, cos i had crashes with my favorite browser FF (at daily bases literally) so i sw to Opera and Chroma with zero issues.
