As a result, the computer will blue screen due to a software or hardware issue. Below is a list of common blue screen error codes and what they might result from.

Common BSOD error codes

  • IRQL_NOT_LESS_OR_EQUAL: IRQL stands for Interrupt Request Level, which means that a program tried to access a piece of memory that the OS was reserving for some special function. As a result, this could point towards a driver issue. You should try updating the drivers of your machine through the device manager. It could be an indication of a hardware error as well.
  • DATA BUS ERROR: Occurs when memory or RAM installed on the computer has an issue. A way to check this run a memory test utility or pull out the RAM sticks to rule out which may be bad. Consequently, if this does not resolve it, the error could also be referencing a piece of faulty hardware.
  • MEMORY_MANAGEMENT: A way to resolve this is to go into your computer’s BIOS and making sure your memory settings are correct. This could happen if the RAM has been overclocked or if it is not getting proper voltage.
  • MACHINE CHECK EXCEPTION: This error can be caused by a CPU that has been overclocked to the point of instability. If this is the case, you may want to lower your overclock settings on your CPU.
  • FAT_FILE_SYSTEM: FAT or NTFS means you have a problem with the hard drive or SSD. This might be as simple as a driver issue. Following this error, you should back up any important data immediately and then run a system file check utility.
  • INACCESSIBLE BOOT DEVICE: The error could be caused by a corrupt sector on the drive or incorrect BIOS settings. The bad sector might be resolved by running Windows Startup Repair or adjusting your BIOS Settings.
  • SYSTEM THREAD EXCEPTION NOT HANDLED: This is more of a general error that could point to multiple things. For example, on the blue screen, look for a file name that failed. This could point you to the driver or program that is causing a problem.
