"Stop 0x50" Error Message While Installing Windows

MORE INFORMATION

1. Disable all caching on your computer, including the CPU cache and L2 cache, in the computer's CMOS settings. For information about how to use your computer's CMOS configuration tool, please refer to your computer's documentation.
   
   If you can successfully install Windows after disabling all caching, try re-enabling each cache, one at a time, to determine the area in which the faulty RAM is located. If you still receive the error message, continue to the next step.
2. Temporarily replace your video adapter. If you can install Windows after replacing the video adapter, the video adapter you replaced is faulty.
3. Temporarily replace the main memory installed in your computer. If the RAM in your computer consists of multiple SIMM modules, you may be able to swap SIMM modules to determine which has the faulty memory.
   
   For example, if you have four modules of 8 megabytes (MB) each, remove two of the modules and try installing Windows again. If the Setup process still does not succeed, swap one of the SIMMs in the computer with one that you removed and try again. Continue this process to determine which of the SIMM modules contains the faulty memory.
