Keyboard beeps and does not type

I have a Dell Inspiron laptop with WIndows Vista BUsiness OS. I am able to type in the password and log in to WIndows but once I am in Windows I cannot type at all. The keyboard beeps and does not type anything. I already tried plugging an external keyboard and same problem. I tried booting in safe mode and same problem. I ran a keyboard diagnostics and it didn't report any errors.

What is going on with the keyboard.

Thank you in advance

I think you mean you get a beep noise from the speaker.

If you are getting to the Windows desktop  and can't do anything with the keyboard but the mouse works it seems you have a corrupt Windows installation.  Could be virus infected also.

Does the mouse still work?

Yes the mouse works and yes every time i press a key on the keyboard it beeps...is not a continuous beeping is just when i click a key.

The pc speaker will beep like that when a key is pressed but the keystroke buffer is already full. Perhaps a key is stuck down and the buffer is filling up. Plugging in an external keyboard won't work because the faulty built-in keyboard is activated first before the usb keyboard. I never tried this, but I am wondering if you can boot a laptop with the built-in keyboard disconnected but with an external keyboard plugged in?

Seems like the keyboard is OK but either a virus or corrupt Windows.

Trouble is doing stuff with a system like this.

If you've got an antivirus solution in the system try running it.

Or try Malwarebytes http://www.malwarebytes.org/ and see what that finds.

Make sure none of the keys have become stuck.
Boot into bios and look for something called keyboard click and disable it,save and reboot.

you can test if the hardware is ok by running it from another OS, like the live Knoppix cd :
ftp://ftp.kernel.org/pub/dist/knoppix/KNOPPIX_V5.0.1CD-2006-06-01-EN.iso

I tested the keyboard on linux and after i noticed it was working I ran a scan with malwarebytes and removed the infections.

Thank you.

I actually thought it was a virus because after I ran the scan I rebooted it and it was back to normal then i rebooted it again and it locked the keyboard again. The problem was that it had the filter keys enabled I had to press shift for 8 seconds and then it would enable the keyboard. I pressed both shift keys at the same time and it disabled the filter keys...Thanks for your help
