STOP: 0x00000100
Description
Some older versions of Windows may show the description as "LOADER_BLOCK_MISMATCH".
This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.
Sample Screen
A problem has been detected and Windows has been shut down to prevent damage to your computer.
The loader block is invalid or does not match the system being loaded.
If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:
Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.
If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

Remove Viruses and Malware
6
Using an Anti-Virus product with the latest pattern files, scan the system for viruses and malware. Often this is called a deep-scan where it looks at every file in the system.
Several software products that handle the detection and removal of Viruses and Malware include Avanquest's Fix-It Utilities Professional and SystemSuite Professional. Other commonly available Anti-virus products are available from Computer Associates, F-Secure, Kaspersky Labs, McAfee, Sophos, Symantec, Trend Micro and others.
While BSoD fatal stop errors are identified by Microsoft Windows, they are often caused by
non-Microsoft applications, drivers and hardware issues.
