Default Reluctant keyboard

I have an old Dell desktop. It is hanging in there but last week the keyboard
stopped working. It is receiving power the lights are green but absolutely no
characters emit from it so I can't do a thing and nothing shows on the monitor except the login which of course I can't do.


None of the function keys are functioning so i can't safe mode, restore, go to BIOS, etc.

I've checked connections again and again, changed USB ports again and again,
cleaned the damn thing but to no avail. I ran it by some forums but struck out.

Your's is always the very best so I should have come first but I'm here now.

I also used other keyboards and nothing doing. I used the Dell keyboard on other computers and it works.

Very puzzling.

Any help much appreciated, really.

Are any of the other boards you've tried PS2 instead of USB? If not, it might be worth trying a PS2, assuming your desktop has this connection.

The only problem is that you have to have the PS/2 keyboard attached when you start the computer. If the Hugheen wants to shutdown his PC in an orderly manner then a PS/2 keyboard will not help with that.

If the keyboard works in another computer but not in this one then that suggests there is a problem with a USB driver or hub.

To have a look at that or to logon you need an input device. So do you have a mouse that is working? If you do you can do everything you need to using the onscreen keyboard.

Also if you're stuck at a password screen on Windows 7 & 8 you can access the onscreen keyboard to login with the mouse. I can't remember if the icon is displayed on an XP login screen.

Thanks for thoughts guys. I kind of agree it must be the driver or hub problem is what to do about that.

Maybe time to send to computer heaven (or hell)

If the hub has died then the BIOS/firmware should pick that up when it does its boot checks.

If it is a driver problem then reinstalling the chipset drivers or only the USB hub drivers might fix it. That reminds me that I have done that before to fix USB problems on an old Dell Dimension I was using.
