The 0×9F error will show on your system whenever the user attempts to boot up their system from scratch, restore it from hibernation mode or restarts it. The error is caused by the "power transition requests" of your system being corrupted and erroneous. These are basically what Windows uses to help control the amount of power flowing to the various hardware components of your system whenever your system is running at a certain level.
This error will typically show in this format:
- STOP 0×0000009F DRIVER_POWER_STATE_FAILURE
- STOP 0×0000009F (parameter1, parameter2, parameter3, parameter4) DRIVER_POWER_STATE_FAILURE
The first step to fixing this error is to update your computer to ensure that it has all the hotfixes that Microsoft have released. It's often the case that Windows will have a series of problems that will be fixed by a variety of updates, which can be obtained by clicking Start > All Programs > Windows Update. This will basically allow your computer to download all the new updates it requires, leading it to run as smoothly and effectively as possible. This may cure the issue for many people, but if not, then you're going to need to repair any potentially damaged hardware, as well as fixing any registry errors on your system.
After updating your system, you should then look to update all the drivers on your PC, as well as fixing any potentially damaged hardware on your computer. On top of that, it's also recommended that you use a "Registry Cleaner" program to scan through Windows and fix any of the damaged / corrupted settings that it has inside. Registry cleaners are popular types of software which are designed to scan through your PC and repair a series of problems that are leading it to run erroneously. The registry database is actually a very important part of the Windows system, which is continually being used to help your computer "recall" a huge number of settings & files for your system. Although the registry is one of the most important parts of your system, it's also one of the biggest causes of errors, and is also one of the main reasons why the 0×9F Error  will randomly appear on your PC (because a particular registry setting has become damaged or corrupted). In order to fix this problem, it's highly recommended you use what's known as a "registry cleaner" program to scan through your PC and fix any of the issues this database has inside.
