Blue Screen Error (BSOD) – Explained, Causes & Solution

BSoD or Blue Screen of Death is a well known problem on Windows based PC. The Blue Screen of Death (also known as a stop error, BSoD, bluescreen, or Blue Screen of Doom), or maybe more properly the ‘Windows stop message’ occurs when Windows detects a trouble or error from where it cannot recover. The operating system halts and diagnostic details are shown on a blue screen and your computer gets self restart.

When this error occurs you see the MSG on your screen something like that.
“A problem has been detected and windows has been shutdown to prevent damage to your computer. If this is the first time you’ve seen this stop error screen, restart your computer.“
Well Wikipedia has defined BSoD as.
The Blue Screen of Death (also known as BSoD or Blue Screen), known officially as a Stop Error or a bug check, is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to crash. The term is named after the color of the screen generated by the error. In Unix-based operating systems, a similar term is kernel panic.
Whenever this type of Blue Screen Error occurs you see a MSG with some codes something like this.
STOP: 0×00000019 (0×00000000, 0xC00E0FF0, 0xFFFFEFD4, 0xC0000000) BAD_POOL_HEADER
The first code represents a specific error, while the others are additional data whose meaning depends on the error code.
There are many causes for this error: Bad dll, incorrect device drivers, bad memory, damaged windows registry, etc. This consistent, despite the fact that less so in newer operating systems, error occurs whenever Windows senses an application, hardware or driver error that will not allow it to continue operating properly. This means that, it occurs quite frequently, for many forms of reasons.
Usually, if you are lucky, the issue will resolve itself with just a simple reboot and you may probably never need to bother about it again. More typically though, the BSOD is a harbinger of trouble and you could end up facing with another and another, In Windows System, stop messages generally occurs cause of following reasons,
  1. Software Program error. Software or device drivers installed in your computer might have errors or problems which cause a stop error, either constantly or under certain conditions.
  2. Hardware errors. In case a hardware device malfunctions or is removed during the operation of Windows, or if your hardware doesn’t fully support the operations that XP expects it to support, a hardware stop error will occur. Outdated BIOS information on older computers may also matter.
  3. Installation errors. The Windows installation process is regarded as the most sensitive time for hardware and disk errors. When there is a problem with your computer’s hardware settings or the media you are using to install, a stop error will more than likely occur.
  4. Startup errors. Damaged system files, hardware and driver errors can all cause Windows to end with a stop message without correctly booting into Windows. An error of this sort will usually require troubleshooting before Windows can be loaded correctly.
  5. Intermittent errors. The most irritating type of stop message, these crop up consistently but apparently randomly. One of the most likely culprits for this include: defective system memory, an overheating processor, dead or dieing hard drive or faulty software and device drivers.
Possible Solutions of BSoD:
Depending upon the causes there may be various possible solutions to resolve this error.
  1. Check your CPU Temperature. If that is above 60C then that may be a cause. CPU overheating is the most commonly known reason for causing BSoD Error. Enable Thermal Throttling Feature from BIOS and CMOS Settings (if your motherboard have)
  2. Remove any new Hardware if you have attached recently (if any).
  3. Clean Corrupted Windows Registries.
  4. Uninstall those software which you have installed recently(if any).
  5. Update Windows Drivers.
Following these solutions may help you to resolve your issue but there may be more possible causes behind this. I mentioned above only most common reasons above.
