The keyboard driver in my Acer has become defect, so I have found the driver on Acers website, and downloaded it to a usb-pen. In device manager I have tried to remove the driver, and restart, but the driver is still marked as defect. So then I have tried to reinstall the driver via device manager, but XP claims not to be able to find a driver that better fits the hardware. So I have no options of forcing a reinstall or something like this. What can I do then? I would have liked to run a chkdsk /f in case there is an error on the harddisk, but I cannot use the keyboard and not an external one either :-(

I believe that wired external keyboard does not need drivers ..still wat you can do is after connecting the keyboard run the motherboard driver cd and check if it works.\ drivers for keyboard are generally needed only in using wirelesss keyboards. Let me know if it works

Thanks Galaxianape! The PC in question is a notebook, so it is the built-in keyboard that causes problems. But trying to add an external USB-keyboard does not work either. It just adds a driver called "HID-keyboard" underneath the driver section "Keyboards" under Device Manager(also an exclamation mark). Unfortunately I am sitting 2200 miles from the original system disks, so I need to find another solution. The problem seems to be that I cannot completely remove this driver. I guess I would need to remove something in the registry as well, but a little blank to what and where. If I try to boot in safe mode does not make the keyboard work either. So it seemms as if I have to get the "launch manager" driver to work.
