If you use the Selective Startup option on the General tab in System Configuration Utility to clear all of the boot entry check boxes and the behavior still occurs, use the following troubleshooting steps:

1. Click to select every check box on the Advanced Troubleshooting Settings tab in System Configuration Utility. To verify the items that are on the Advanced Troubleshooting Settings tab:
   • Click Start, click Run, type msconfig.exe in the Open box, and then click OK.
2. On the General tab, click Advanced, click to select each check box, click OK, and then restart your computer when you are prompted to do so.
3. Use the restoring by halves process to isolate the behavior. Many of the behaviors that you can isolate through this process are related to hardware or driver compatibility issues. When you isolate the behavior, contact the hardware or software manufacturer to inquire about an updated driver or about compatibility issues with Windows 98.

    Note each static .vxd file and respond with No to avoid loading each file. View the following partial list of Microsoft static .vxd files:

    Static .vxd file	Provides support for
    Vnetsup.vxd	Microsoft Networking
    Ndis.vxd	Microsoft Networking
    Ndis2sup.vxd	Microsoft Networking
    Javasup.vxd	Microsoft Java
    Vrtwd.386	Clock
    Vfixd.vxd	Video Phone helper
    Vnetbios.vxd	Microsoft Networking
    Vserver.vxd	Microsoft Networking
    Vredir.vxd	Microsoft Networking
    Dfs.vxd	Microsoft Networking

    Msmouse.vxd	Microsoft Mouse

12. If the behavior no longer occurs, repeat steps 1 through 6, but press ENTER to respond with Yes to each of the files in the previous list. If the behavior no longer occurs, the behavior is not related to any of the static .vxd files in the list.
13. Use the restoring by halves process to isolate the static .vxd file that is causing the behavior.
14. Delete the incompatible static .vxd folder under the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD registry key.

Static .vxd files are used to load virtual hardware and software drivers. Many third-party manufacturers add their own static .vxd files.
