I've just resurrected an old MSI KT6 delta motherboard after my current board died. Everything works fine up to the point windows loads. The keyboard works fine when using it in BIOS, but the moment windows loads the keyboard lights go out and none of the usb ports work.
Sounds like your O/S was damaged when the old MB failed. I'd boot the computer with yoru system disk and run a scandisk or, in the case of Win Vista or 7, choose the option to repair Windows.

Slim, Other than saying well it was a good couple years for the board lets just verify: Have you tried a different keyboard? Check device manager and see if you uninstall the keyboard and then reinstall it. Or have you recently installed any new devices that may have taken the resources away from the keyboard plug? If not get a usb keyboard and make sure you info is backed up...just in case. Good Luck, Tim

Do you have an IDE hard drive fitted as well.
If so remove it as I have found out that unless setup properly IDE and SATA do not mix

VIA needs to stop making USB chipsets... lol... Are you sure you have USB legacy support enabled? Moreover, the default Windows XP drivers are not error free when used with a VIA Rev 5 USB Host Controller because it's actually a VIA Enhanced Host Controller. Every time I have USB problems with the VIA Enhanced Host Controller I go to there website, download the driver, and it usually fixes the problem.
USB 2.0 (VT6202, VT6212, VT6214/L)
Moreover, I have plugged in a Microsoft Wireless Optical Mouse and Windows XP could not detect it until I installed Microsoft Intellipoint; if you can believe that. Try also installing the mouse drivers as well...

You're "stuck" -- if the circuitry for the PS/2 keyboard and mouse is not working, and if it does not recognize a USB keyboard, the motherboard must be replaced (by an identical moetherboard, if you can find one, or a "newer/better" motherboard that takes the same CPU and RAM as your current motherboard).
