Windows 7: Windows 7 64 bit does not detect keyboard....

Windows 7 64 bit does not detect keyboard....

Just installed Windows 7. Runs like a charm, BUT when I reboot for the first time it comes back to the login screen with no keyboard. The keyboard lights are on, just wont detect it. Mouse works fine. Can login to the system with onscreen keyboard and everything else works fine. Tried new keyboards and ports. As soon as I unplug it and replug there are no lights on the keyboard at all. Tried uninstalling keyboard drivers and reinstalling but still no luck. Did 2 fresh installs of OS and same thing happens everytime. The keyboard works fine after the setup is complete, but once I reboot, no keyboard. Dell Tech support told me Windows 7 is not compatible with some USB keyboards. I think that is BS. Went out and bought a new Microsoft wireless keyboard that is made for Windows 7, still no dice.

I then installed Windows 7 32 bit, now everything works fine. Can reboot and keyboard works fine. This is OK for now, but I would really like to use all of my 4GB of RAM in 64 bit. I have a Intel Core 2 Quad, so 64 bit should work.

Try updating your chipset drivers on x64. It certainly sounds like a driver issue, doesn't it?

Have similar problem after installation of Adobe Acrobat Extended Pro. At Logon screen no mouse and no keyboard works. Have only USB connection on my Intel board DP55KG. Tried cable wireless (Logitech) and Bluetoth. Tey all work at BIOS and Boot level, but as soon as Logon screen appears, they are both dead. Repair option (also with booting from Windows 7 DVD) did not help. Copying of USBxxx.sys driver back to hard drive (windows\system32\drivers) did not help. Any suggestion??? (without going through tedious "new installaton" ??)

If you are using a usb keyboard, go into mobo bios and make sure usb keyboard is on.

Thanks for your help,
but there is no special usb keyboard entry on Intel DP55kg bios. Only usb legacy and 12 different ports to switch on or off.
Anyway is the keyboard detected at boot up sequence and also F8 for safe boot on windows works fine. The problems starts, when Windows 7 is up and wants a "Ctrl-Alt-Del" entry.

Do you have any PS2 ports on mobo.
If so, get a usb to PS2 adapter and check keyboard that way. Just an idea.

In bios is there a selection for using 64 bit OS?
In bios can you select wake on keyboard?

The bios has nothing to do with using a x64 OS.

Wake on keyaboard would only turn the computer on from sleep mode (S3 mode) not enable windows to see it if it can't when running.

Its a usb driver issue, you need to get a ps2 adapter to get it working, or if your mouse works you can use the onscreen keyboard to get to the motherboard manufacturers site and grab the latest chipset drivers.
