The dreaded BSOD 9F driver power state failure has been a problem for the last few months. HP dv7 laptop is about 1 1/2 yrs old. BSOD is random; sometimes a week can go by and at others multiple times in a day. I updated the BIOS to F.1B, the radeon graphics hd6770m driver is 8.830.6.2000 4/12/2011 with no improvement. sevenforums.zip is attached. What else do you need to know?
