Ok, so basically my other computer is a Dell Optiplex 330, however, it has a sticker on it that says n series. Whenever I search the computer though every optiplex 330 that comes up looks the same, except they all have core 2 duo processors, while mine has a pentium processor, and yes the processor is stock, the computer has the pentium sticker. I've tried searching the n series thing, but I only get random irrelevant results. What does the n series thing mean, and why the does my computer not show up on dell or anywhere on google???
