Keyboard stopped working computer locked

oh.. and yes i have unhooked and rebooted several times..  

WHOA!! Before even considering a reinstall, there are other options to try that aren't so "invasive" as what's been suggested.

please do tell of those options!!!   I do not want to reinstall cause i will have to loose info and pay to have it done..

I tried the first steps (F9-F10) and it didnt work either.. I cant get past the lock screen to do a back up and I have a slave drive that i can unhook before i was to reformat that has most of my stuff on but I dont have the disk to do a reinstall with..  and i have some things that wernt moved over that i would not be able to part with. is it possible to hook up the main hard drive to the slave drive connection and then choose to book from the slave drive?  Would this work to get the password removed..and maybe see whats going on with it?

could this be a virus or what.. i have not had any problems what so ever from this computer or operating system.. not done an update or anything.. I am confused on how this could have happened.. how to prevent it in the future..

Was old keyboard USB?

Would help if we knew exactly which PC you have. Isn't it marked on the front, around the power button?

Or use your Service Tag number at Dell's support site (link at very top of this page). Click Drivers/Downloads on that page and enter your Service Tag on left side and click Submit. It should show you the model number along with a list of drivers. Do NOT post your Service Tag number here.

And which Windows XP Service Pack? SP1, SP2, SP3?

Try this:

Reboot and press F8. Pick "last known good' from the menu instead of safe mode. If that works, shut down normally and reboot normally.

the old keyboard was the factory type with the round pink end.. the new one is a usb.. both work in bios..

my computer is a dell dimension 8110 with xp home edition.. unsure about the service pack..

and i have tried to reboot with F8 and last known and it wouldnt go through.. gave me an error message.. I know this isnt much help but i couldnt find my service sticker anywhere even took the cover off.

I don't see a Dimension 8110 listed. I suspect you mean a B110. Round keyboard plug would mean that's a PS/2 keyboard.

Exactly what error message did you get after pressing F8? And was that with old PS/2 keyboard or new USB keyboard?

Where are you connecting USB keyboard? USB keyboards should always be connected to USB port on rear of the tower.

The Service Tag should be on a sticker on the side of the tower.

yes sorry it is the B110. and yes the PS/2 (wasnt sure what it was called)

error message is given when i press F8 and then choose to boot from the last good boot {error message : couldnt start missing or corrupt  \windows\config\system\ }  

this was with the new keyboard that was plugged into the back usb port.  I have not tried F8 reboot with the old keyboard.. and the service sticker must have been removed all i have is the one with the product key.

First try the old keyboard, but I suspect it still won't work either. Disconnect USB keyboard and be sure to power off before connecting the PS/2 keyboard. Then reboot and try F8 - Last Known Good.

The message you're getting means you'll probably have to run a Repair/Reinstall of Windows. Personal files should be ok, but you will have to reinstall a bunch of Microsoft updates. But at least the Repair shouldn't delete your personsal files or other installed software.

To run the Repair/Reinstall, you're going to need a Dell Windows CD with the same version (eg, XP home) and at least the same Service Pack (or newer) as is on the hard drive. Eg, XP home SP2 CD with home SP2 on hard drive, or XP home SP3 CD with either home SP2 or home SP3 on hard drive. If you don't have the disk, and you're in the US, you can order it from Dell here.  I presume XP disks are still available, and Dell may charge you for it. 

you were correct.. the old keyboard didnt work either... I will just have to contact my repair guy and pay him to work on it.. thank you so very much for trying to help me with this issue..

You can do this yourself as long as you have the Windows CD. It's not difficult and we can walk you through the procedure.

And we won't charge you anything!  :emotion-1:

Good luck.

Many systems do not work in safe mode with USB Keyboards.  If you can get to F2 then you can figure out which model Dell you have.  

Perhaps Dimension B110 DE051

Identify the Computer Model Using the Model Code

On Sept 26, 2005 the System Setup program on certain Dell Dimension™, Inspiron™, and XPS™ computers was changed to display a model code instead of the computer model name. The Resource and Driver CD also lists the computer by this code. This may cause confusion when identifying which device drivers to install. If you are unable to identify your computer using the model code, refer to Table 1 below to determine the model name of your computer.
