APC_INDEX_MISMATCH Error Code 0x00000001

This STOP error can occur during start-up or at other times. The 8 digit hexadecimal number 0x00000001 means the error APC_INDEX_MISMATCH which may be caused by the following:

Causes of the occurrence of

  1. This error could pop up when a CD or DVD is inserted into the drive
  2. A kernel-level application or device driver running in kernel mode created a mismatch of thread and asynchronous procedure calls (APC) indexes. This is possibly due to a file system mismatch in the number of processes that got in the critical area as compared to those that left. Allowing the software application to run at this point will corrupt or damage the system.
  3. This could be due to recently added hardware or software application issues.
  4. This STOP error sometimes occurs after the computer transitions into to sleep mode repeatedly (by customer usage).
  5. This error also occurs when the computer system uses the Windows Vista Aero color scheme.
  6. Problems in the Windows system file win32k.sys can cause this STOP error.
  7. Memory corruption can also create these problems.
  8. Sometimes, when we unlock the computer and login to the default desktop this STOP error shows up.
  9. Too much RAM (> 2GB) may exceed motherboard and BIOS capacities and develop this STOP Error.
  10. This problem can also take place in a secure desktop setting (when we lock the computer) where an application has signed up an “event hook” using an Application Programming Interface

Solution

1. Verify that all your hardware is compatible with the Vista operating system.

2. If this error showed up when the computer was restarting, go to Step 8. If the computer was operating normally when this error occurred, then continue to Step 3.

3. If the error appears during restart (and the restart is successful in spite of the error) , set the Windows Memory Diagnostic to get more details about the problems during restart. Then go to Step 6.

a. Click on Start->All Programs->Accessories. Right-click on Command-Prompt and choose “Run as administrator”
b. Enter mdshed.exe at the command prompt. Schedule the tool to run at the next restart.

4. Check the “Problem Reports and Solutions” page or VISTA. Click on Start->Control Panel->System and Maintenance->Problem Reports and Solutions. This facility searches online for device driver updates and solutions to problems caused by external hardware or software.

5. Verify that all the software updates are installed for the current Operating system as well as on all device drivers and external third party software on the system.

6. Try to restore the system to a previous restore point. Click on the Windows Start button and type “System Restore” into the Search field. The System Restore application comes up. Choose a restore point and continue to restore system.

7. Try to restart the computer again. If you cannot restart it using the mouse or keyboard options, shut down the computer by pressing down the manual Power button for a few seconds. When the computer has completely shut down, press the button again to restart the computer.

8. Choose a keyboard layout and log in using username and password. You will need administrator password if it is set on the system. If you have never set it, then just click on “Continue”.

9. As the computer restarts, press and hold the F8 key before the Windows Logo appears.

10. Choose Startup Repair from the menu for “System Recovery Options”. The Startup Repair process will try to repair the computer.

11. If this does not solve the problem, check the CD-ROM driver and try to install another one. Open up the chassis and check the motherboard. Reseat the memory chips. Check the power supply. If you have testing equipment for the hardware, use them to detect any hardware malfunctions

12. If none of the above works, you may have to reformat the drive and re-install the operating system.

13. Use the arrow keys to select “Repair the computer” in the “Advanced Boot Options” menu.
