Hi, I have a custom built computer that I have taken apart a few times and put back together (trying out different parts and such) but I am no where near experienced enough with computers. My ex put it together originally for me. I put it back together for the most part just fine, with the exception of my CDRom. First time it didn't work at all, second time the actual CDRom works it is just not being read by my computer. Like under my computer nothing is listed for the CDRom and I am not sure how to make it work again, and I really need to get it to work again. Could it be the actual connections, or is there something I need to do when I turn the computer on? Some help would be very much appreciated. Sorry if this isn't the right category to put this under.
