I turned my HP8540w on last night when I lost power. I did notice that there was a message on screen saying that there was an update to Registry just before the power was lost. Now laptop won't start up, goes to blue screen and says it has to close down. Run Launch Startup Repair and it says that it can't repair this computer automatically and then computer turns off. I have tried all sorts starts and checks from Startup Menu to no avail. The only code I get is 0x8oooffff
