Start the problem solution, use the device manager to try

Windows Device Manager is a management tool that you can use to manage devices on your computer. You can use “Device Manager to view and change device properties, update device drivers, configure device settings, and uninstall devices. Use this tool to resolve any possible device conflicts or to identify incompatible devices that may cause startup problems.

To start <;Device Manager>, follow these steps:

Click Start, right-click My Computer, and then click Manage.

Expand System Tools and click Device Manager.

The devices installed on your computer are listed in the right pane. If a symbol appears next to the device, there may be a problem with the device. For example, a black exclamation point (!) on a yellow bottom indicates that the device is in a fault condition.

Note: To disable a device in <;Device Manager", right-click the device and click Disable.

Investigate possible device conflicts. To do this, double-click the device in the right pane, and then click the Resources tab.

If there is a device conflict, the device will be listed under the "collision device list".

Please note the <;Use automatic settings” checkbox. If Windows successfully detects the device, this check box will be selected and the device will function properly. However, if the resource settings are based on “basic configuration n ” (where n is any number from 0 to 9), you may need to change the configuration. To do this, click on a different basic configuration in the list or manually change the resource settings. WARNING: This procedure may require changes to the computer's Complementary Metal Oxide Semiconductor (CMOS) settings and basic input/output system (BIOS) settings. Incorrect changes to the computer BIOS can cause serious problems. Changing your computer's CMOS settings is at your own risk.

If Windows cannot resolve resource conflicts, verify that your computer is configured to allow Windows to enumerate devices on your computer. To do this, enable the “Plug and Play OS> setting in the Setup tool of your computer's BIOS. To change your computer's BIOS settings, see your computer documentation or contact your computer manufacturer.

If you have identified the device in question, disable it and restart your computer in normal mode.

If your computer starts up properly, the device you disabled might be the cause of the startup issue.

Make sure the device is listed on the Windows Server 2003 Hardware Compatibility List (HCL) and is installed correctly. Also, report the phenomenon to the manufacturer and get information about possible updates that can resolve startup issues.
