I've had this Hell, er, I mean, Dell, for three and a half months. It was working wonderfully until I decided that I was going to give the computer to my g/f as a gift, so she would have something a tad more powerful than the Celeron-riding Compaq she has now.
As soon as I tried to boot the machine at home so I could load programs and change settings before I actually gave it to her, it started to throw a hissy fit at me. It gave me a beep code of two beeps, and said "Primary Drive 0 Not Found."
Now, as a fellow geek (I work at CompUSA and go to school for Microsoft), my first troubleshooting item was the HD itself. It spun up fine in my other machine, and I could read every file. It doesn't whine, click, or squeal (unlike the Master HD in my Compaq, which, oddly enough, still performs like new). Thus, the HD was not the problem.
Second idea: IDE Cabling. I swapped the IDE cabling for two others, one which was brand new and one that I know for a fact works, because it's the cable that connects my Compaq's brain to the board, I just swapped it out to help me troubleshoot. I still got the same error.
So, I went into the BIOS of the Dell (a Dimension 3000, btw, for those of you who were wondering) and "ALT+E" and "ALT+F"'d to clear and reset it. Still, nothing.
The only thing left I could think of would be, you guessed it, blown IDE controller. I contacted Dell and harassed them until they sent me a new mobo, and I plugged it in.
SAME ERROR! I can't get rid of it! Does anyone have any ideas at all?
