I have a Dell Dimension 4700c running a fully patched version of Windows XP.

This morning, it decided that Windows would no longer recognize the USB keyboard and mouse. Both the keyboard and mouse work fine in selecting a boot mode, changing BIOS options, using the XP setup disk, in a BartPE environment... basically everywhere except a fully booted Windows.

I have tried Safe Mode, as well as using a different keyboard and mouse. I have also switched to different USB ports. There are no PS2 ports to try PS2 devices on.

I tried booting from a Windows XP install CD, but it doesn't see a previous version of Windows, hence no option to go to a repair console.

I think running SFC or a system restore may help, but can't figure out how to get to those. Any suggestions on repairing the current install? I'm hoping to avaoid a reinstall.

Sounds great, but can't get logged in without a keyboard or mouse!

that is a weird one that i've seen here and never learned the answer. i thought you could do a system restore from recovery console but i see i am mistaken. as you probably know you can do it from a command prompt, so if no joy with safe mode, try f8 boot and pick safe mode command prompt only. here is how:
steps to use recovery console:

SUMMARY
When a USB device is repeatedly inserted and removed, the USB port may stop responding. This article describes how to resolve this problem with a unresponsive USB port.
Back to the top

SYMPTOMS
If you quickly and repeatedly insert and remove a USB device, the USB port may stop responding. When the port is in this state, it no longer recognizes any USB device.
Back to the top

CAUSE
This problem may occur because of a race condition in the Selective Suspend feature of USB. Microsoft and the hardware vendors that manufacture the chips that are used for USB have investigated the problem. However, the results have been inconclusive because of the intermittent nature of the problem.
Back to the top

RESOLUTION
To resolve this, follow these steps: 1. Start Device Manager.
2. On the Action menu, click Scan for New Hardware.
If this does not resolve the issue, you have to restart the computer. In some cases you must use Device Manager to disable then re-enable the device to get it to recover from this unresponsive condition.

I can't install the recovery console or update drivers, as I don't have a keyboard and mouse while in Windows.

In addition of the preview answer, he?s right BUT!!!
How do you do this without mouse and keyboard? The solution is to try to use an old serial mouse.

This really sounds like a USB port failure. Check
that the kayboard and mouse are inserted properly and fully engaged in the slots. Try
another USB keyboard, if no luck there, then
the USB has failed. In most cases, the USB
chip is part of the system board, and will
require replacement. Be sure the connector
on the end of the cable is clean.
