Hi, I've seen various posts on the machine restarting issue, but none of the solutions seem applicable to mine: I've checked for all those softwares and found none installed on mine. I too get the BC error with product 256_1 after the machine restarts. Attaching the dump. I hope someone could tell me what's causing my machine to restart. I've scanned my disks several times, but the problem continues. Could it be the Intel Graphics media accelerator that I have?
