This behavior can occur if a hardware component malfunctions, or if
there are damaged or incompatible drivers installed.

To try to resolve this behavior, use the following troubleshooting
techniques. Because Windows can display only basic error messages when
hardware malfunctions occur, troubleshooting can be difficult. Most
equipment problems center around the motherboard, the RAM on a
motherboard or on an adapter, or the cache memory on a motherboard or on
an adapter.

To troubleshoot basic hardware problems, try one or more of the following:
Back to the top    Back to the top
Check the Memory
Remove any extra memory modules that are in the computer, leaving only
the least amount that is required for the computer to start and run
Windows. Restart the computer to see whether the error messages persist.

If the error does not reappear, the issue is isolated to one or more of
the RAM modules that you removed from the computer. Continue to remove
and replace the minimum amount of RAM required, using the memory modules
that you removed. When the error returns, you have isolated the
individual memory module that is responsible for the problem.

This process may require you to restart your computer several times to
pinpoint the specific memory module that is not working correctly.
Replace the defective RAM module.

Microsoft has released a software memory diagnostic tool, Windows Memory
Diagnostic. Windows Memory Diagnostic tests the Random Access Memory
(RAM) on your computer for errors. To download this tool, visit the
following Microsoft Web site:

Check the Adapters
Remove any adapters that are not required to start the computer and run
Windows. In many cases, you can start your computer with only the drive
subsystem controller and the video adapter.

If the error message does not appear, one of the adapters that you
removed is the source of the problem. Reinstall each adapter separately,
restarting after each adapter is installed, to see whether the error
returns. If the error does not return after you reinsert all of the
adapters, it is possible that one of the adapter cards just needed to be
reseated. After your computer is running again, monitor the computer to
make sure that the error does not return.
If reseating the adapters does not solve the problem, replace the
adapter that is causing the error.

Check the Computer BIOS/Configuration
Verify that you have installed the latest revisions for your computer's
BIOS or firmware configuration software. Go into the BIOS and set load
Fail-safe defaults or BIOS defaults, disable any antivirus protection in
the BIOS, and then set Plug and Play OS to No.

The type of hardware that your computer uses and the design of the
motherboard determine what part of your computer's firmware can actually
be updated. Various manufacturers provide diagnostic tools for
Update the BIOS, the firmware, and/or the EISA configuration.

If none of these procedures isolates or resolves the issue, the problem
can be narrowed down to the motherboard, drive subsystem controller,
hard drive, or the video adapter. Advanced RAID or other caching
controllers can have RAM, processor chips, or both that could also be
the problem. If the simplest configuration contains one of these
advanced adapters, resolving the problem may require use of additional
troubleshooting or diagnostic software, possibly using duplicate hardware.
