USB Keyboard Not Working

Specs: XP Pro, Intel 2.60 G./888MB
I'm working on a Dell C521 and the problem being that the USB Keyboard does not work. I have read several posts and found not solution. The keyboard will work on boot up. I can get into the setup and made certain the usb/keyboard setting were normal/facturey. I can also get into safe mode, guess what, the keyboard works in safe mode. As soon as I attempt to boot into XP no keyboard. I have uninstalled USB/Keyboard drivers with not luck. I have tried several working keyboards, no luck. I also checked with logiteck and no software is required for this particular model.
Please advise. Thank you.

No USB drivers are required in WinXP. What you may need to install are motherboard chipset drivers. I am guessing that your USB ports are not functioning at all. Go to the link below to get ALL the drivers for your unit. Download them all and burn to disk.

Apparently this is a slim tower desktop computer.

When some USB things work in Windows but others don't, you may need to use a different USB port, or your PS may be faulty and is not supplying enough 5v for USB (smaller propreitary sized PSs are more likely to malfunction) or you may have an IRQ sharing problem you need to fix and then re-load the USB stack.

Don't you think your advice is a little severe at this point?
