keyboard drivers on vista

goulden · 05-15-2008, 12:40 PM

I installed some RAM the other day and afterwards my keyboard wouldn't work

the keyboard works fine on other computers and other keyboards have been tried on the computer with the issue. it's a usb keyboard and my pc has no ps/2 port.

I'm using a dell dimension e521 running vista home premium

what i've done so far:
- tried removing the ram but it made no difference
- tried system restore to a time before the issue, it made no difference
- the keyboard works in the bios setup
- it doesn't work in safe mode
- i can press f8 at the splash screen during boot and get into which boot mode i want to use
- there is no keyboard listed in device manager

- if i start in safe mode, plug the keyboard in after it has booted it detects the new hardware but gets to a point saying:
"the driver installation file for this device is missing a necessary entry. this may be because the INF was written for Windows 95 or later. Contact your hardware vendor"

- i can't find my original dell xp discs or my vista upgrade disc if they would be needed

any ideas?

Hi, what kind of keyboard do you have, as usually any OS will install default kybd drivers until you install your own if needed.
Have you tried changing the battery and/or pressing the little connect button which will be on the underside of the keyboard?
