I have a Dell Inspiron 1000. It started to beep all of a sudden and type 666666 repeatedly (as if stuck) when I am in Word or any text block. I've replace the keyboard several time. Didn't work. Now the USB keyboards does the same. The system beeps when it completes the post. Diagnostic says the keyboard needed replacing although I replace it. Any help would be appreciated. Thanks.

Hi, this is my first time on here. I'm not that great with computer knowledge, but I have a Dell Inspiron 1000, and I've had it for about 3 years. Just recently the backlighting has gone out, and then will come back on at random. Earlier today, the computer just turned off a few times. I'm able to use it for now, but the computer is really silent, and its never done this before.
