I have a HP pavilion PC and was experiencing BSOD every 2 or 3 days, PC would just shut down for no apparent reason with no pattern to the shutdowns. Just over a month ago I happened to be looking at the available driver updates on the HP site and noticed one for the bios, so I downloaded and installed it. From that day I have had no BSODs.
Thought this might help someone in similar situation with same PC
