Keyboard and Mouse not working - Win 2000

[msal]

I have a PC (PIII 600, 128Mb Ram, 15Gb HD) running Windows 2000 with Service Pack 2 which has been working fine for over 8 months until today. After rebooting the PC, it got to the "Press Ctrl Alt Del to login" screen but neither the keyboard or mouse were working. I restarted the PC again, and the keyboard appears to work fine, I can get into and move around the BIOS setup, F8 also works, allowing me to selected different ways to start Windows.
The keyboard stops working as soon as it get to the black screen were it says "Starting Windows" which has the white bar accross the bottom. From this point on, the keyboard does not respond at all - Num Lock etc... does not work.

Several keyboards (which all work on other PC's) have been tested and failed to make any difference, the only thing which did work was a mouse when it was connected to the USB port. If I leave the keyboard or mouse unplugged from the PS2 port on start up, I get a message informing me that no mouse/keyboard has been detected which would indicate that both work fine to start with.

I have tried all Safe Modes, Last Known Good Config and Debugging Mode but the keyboard & mouse still didn't work.

No new software has been installed recently.

I hope some one can help.

check your event log for i8042 port errors. You using intellimouse/intellipoint drivers?

Uninstall those microsoft mouse software pieces, and just try standard PS/2 mouse device, and check that those are set in control panel.

Use the USB mouse you had to access those if you can. You may also want to try the last known good configuration when you press F8.

Lots of possibilities here..hope you can narrow some of them down. Cant rule out the motherboard either.. pbxman

After many tries at resolving this problem, I took the easy option and reinstalled Windows.
