SYMPTOMS
While you are installing Windows NT 4.0, your computer may stop responding
(hang) while displaying the following error message on a blue screen:
STOP: 0x00000050
PAGE_FAULT_IN_NONPAGED_AREA
CAUSE
This error message may be caused by faulty memory (RAM) in your computer.
RESOLUTION
To resolve this issue, replace the faulty RAM.
MORE INFORMATION
The faulty RAM could be located in any of several areas, including the
secondary RAM cache, the video RAM, or the computer's main memory. To
determine where the faulty RAM is located, use the following steps:
- 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 NT 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.
- Temporarily replace your video adapter. If you can install Windows
NT after replacing the video adapter, the video adapter you replaced
is faulty.
- 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 NT 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.
