I have a problem as my laptop crashes following a period of inactivity or when i try to shut it down. I get the BSOD. I tried to update the service pack (pack 1), but that also fails with the error, driver power state failure. I have tried to look at and understand the dump file following a BSOD and it appears there might be a problem with ntoskrnl.exe. I attach the dump file in the hope someone out there can make more sense of it than me. Any suggestions on how to rectify my problem. Incidentally, i have only recently loaded windows 7. Prior to that I was using Vista with few problems.
