3. CAUSE
The symptom occurs due to the abnormal behavior of ntvdm.exe, the Windows system module.
We have found that this is caused by a defect in the BIOS or UEFI on the personal computer.
3.1 Investigation Result
As a result of our investigation, we found that the ntvdm.exe loops infinitely.
(1) Analysis result
The following explains the result of analysis. The addresses differ depending on the manufacturer of the
personal computer.

(2) Conclusion
The address that goes into the infinite loop may be processed by the BIOS or UEFI option.
The problem may occur in the BIOS or UEFI of the graphic function.

3.2 How to Check the Operation of "ntvdm.exe"
The operation can be checked by following the procedure below.
1. Right-click the taskbar of Windows, and then click [Start Task Manager].
2. Select the "Performance" tab in the Windows Task Manager.
3. Check the number of graphs (number of cores) in "CPU Usage History".
Example) Number of cores is '4'
4. Select the "Processes" tab in the Windows Task Manager.
5. Check the value in "CPU" of "ntvdm.exe".
Example) CPU usage of one core is '25'
6. Calculate the CPU usage by multiplying the values which have been obtained in Step 3 and Step 5.
If the CPU usage is around 100%, it indicates that the error is caused by a high-load processing of the
ntvdm.exe.
4. CORRECTIVE ACTION
We have concluded that the MELSOFT products can be installed correctly by modifying the BIOS or UEFI.
If the symptom occurred, please contact the manufacturer of the personal computer used with this bulletin
attached. Obtain the appropriate BIOS or UEFI for your personal computer.
