BSOD, or Blue Screen of Death, is a well-known term associated with the blue screen error in Windows. This error screen is displayed when the system crashes when a fatal system error occurs. Usually, BSOD appears only once, and the system fixes the problem after a restart. However, sometimes the error is too serious and the system cannot fix it automatically. Having said that, you will be stuck in a loop and see a BSOD every time you try to start your computer. This kind of looping also means that you won’t be able to log into your computer. In such cases, you will need to fix the error in order to use your computer again.

BSOD is indicated by an error message or error code. If you are here, it means that you have encountered a driver power failure error or error code 0x0000009F. Both errors are the same. Typically, if you put your computer in hibernation mode and then bring it out of hibernation mode, some devices do not wake up in time and do not respond at all. In this case, the system hangs and displays a Driver Power State Failure error.

However, there are many other reasons for this error. Sometimes BSOD will display this error along with the name of the file causing the error. In most cases, this will be ntoskrnl.exe.

Other reasons that can cause this error:

  • Faulty NVidia video card driver
  • USB device failure
  • Failed to start/run
  • Usage errors – Photoshop, Autocad, Kaspersky Anti-Virus, and McAfee Anti-Virus.
