Keyboard and Mouse Stop Responding When You Upgrade to Windows XP

When you upgrade your Microsoft Windows 98-based computer to Microsoft Windows XP, the keyboard and mouse may stop responding. This problem occurs when the Setup program is at the Windows XP "Welcome" screen.

This problem can occur if you have a Universal Serial Bus (USB) mouse or trackball device that is plugged in the PS/2 port on the computer. This problem can also occur if a serial mouse or trackball is plugged into a PS/2 port.

This problem can occur if your computer needs a Basic Input/Output System (BIOS) upgrade or if there is an incompatible or outdated version of the Microsoft IntelliPoint or Microsoft IntelliType program installed when you upgrade to Windows XP.

To resolve this issue, follow these steps.

Step 1: Upgrade the Computer BIOS

Contact your computer or motherboard manufacturer to inquire about possible upgrades to the computer BIOS. For information about how to contact computer hardware manufacturers, visit the following Microsoft Web site:

WARNING: Incorrectly updating (flashing) the computer BIOS may render the computer inoperable.

Step 2: Plug the USB Mouse into the USB Port

Plug the USB mouse or trackball device into the USB port, and then restart the computer. Both the mouse and keyboard are correctly detected by Windows when you restart.

Step 3: Upgrade to the Latest Version of the IntelliType and IntelliPoint Programs
