Blue Screen Of Death

The Blue Screen of Death (BSOD) , officially a STOP Error , also known as Deadscreen, Blue Screen Error, Bluescreen, or 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.

Stop errors are hardware , updates and driver related, causing the computer to stop responding in order to prevent damage to the hardware or data. In the later versions of Windows (Windows NT to Windows 7) the screen presents information for diagnostic purposes that was collected as the operating system performed a bug check.

Blue Screen Of Death In Windows XP , Vista and Windows 7.

Causes :

Blue screens are typically caused by software errors in device drivers : in NT-based Windows systems by poorly written device drivers , and in the Windows family of operating systems by incompatible DLL driver files or bugs in the software kernel of the operating system.They can also be caused by physical hardware faults , such as faulty RAM or power supplies , overheating of components , or hardware which is run beyond its specification limits (Example overclocking in Processor's).

These errors have been present in all Windows-based operating systems since Windows 3.1. OS/2 suffered from the Black Screen of Death (Bl.SOD or KSoD), and early builds of Windows Vista displayed a Red Screen of Death.

Resolution :

The most important Blue Screen of Death troubleshooting step you can take is to ask yourself what you just did.

Did you just install a new program or a piece of hardware , update a driver , install an update , etc. ? If so , there's a very good chance that the change you made caused the BSOD.

Undo the change you made and test again for the STOP Error.Depending on what change you made , some solutions might include :

• Restart and then Startup using Last Known Good Configuration to undo recent registry and driver changes.
• Use System Restore to undo recent system changes.
• Roll Back device driver to version prior to your driver update.

Verify that a minimum amount of free space is available on your Windows partition. Blue Screens of Death and other serious issues, like data corruption, can occur if there's not enough free space on your primary partition used for the Windows operating system.

Note : Microsoft recommends that you maintain at least 100MB of free space but I regularly see problems with free space that low. I usually advise Windows users to keep at least 15% of a drive's capacity free at all times.

Scan your computer for viruses. Some viruses can cause a Blue Screen of Death, especially ones that infect the master boot record (MBR) or boot sector.

Important : Make sure your virus scanning software is completely up to date and that it's configured to scan the MBR and boot sector.

Apply all available Windows service packs and other updates. Microsoft regularly releases patches and service packs for their operating systems that may contain fixes for the cause of your BSOD.

Update drivers for your hardware. Most Blue Screens of Death are hardware or driver related so updated drivers could fix the cause of the STOP error.

Check the System and Application logs in Event Viewer ( 7 / Vista / XP ) for errors or warnings that might provide more clues on the cause of the BSOD.

Return hardware settings to default in Device Manager. Unless you have a specific reason to do so, the system resources that an individual piece of hardware is configured to use in Device Manager should be set to default. Non-default hardware settings have been known to cause a Blue Screen of Death.

Return BIOS settings to their default levels. An overclocked or misconfigured BIOS can cause all sorts of random issues, including BSODs.

Note : If you've made several customizations to your BIOS settings and don't wish to load the default ones then at least try returning clock speed, voltage settings, and BIOS memory options to their default settings and see if that fixes the STOP error.

Make sure all internal cables, cards, and other components are installed and seated properly. Hardware that's not firmly in place can cause a Blue Screen of Death so try reseating the following and then test for the STOP message again:

• Reseat all internal data and power cables
• Reseat the memory modules
• Reseat any expansion cards

Perform diagnostic tests on all hardware you're able to test. It's highly likely that the root cause of any given Blue Screen of Death is a failing piece of hardware:

• Test your system memory
• Test your hard disk drive

If a test fails, replace the memory or replace the hard drive as soon as possible.

Update your BIOS. In some situations, and outdated BIOS could cause a Blue Screen of Death due to certain incompatibilities.

Start your PC with essential hardware only. A useful troubleshooting step in many situations, including BSOD issues, is to start your computer with the minimum hardware necessary to run the operating system. If your computer starts successfully it proves that one of the removed hardware devices was the cause of the STOP message.

Tip : Typically, the only necessary hardware for starting your PC through to the operating system includes the motherboard, CPU, RAM, primary hard drive, keyboard, video card, and monitor.
