Death of my Laptop

Ok, I have a DEll C610 Latitude. It was working just fine, then it just shutdown and now will not boot at all. I swapped out the HD and memory and still nothing. When I power it up I get 2-beeps, and that's it. I looked for the post codes but it says it could be anything from memory to motherboard. Any clues out there??? Thanks!

 

I was going to say to look up the beep codes, but you did that. You changed the RAM so we can assume its not that for the moment. What else can be ruled out from the beep codes? Also, what did Dell support say? They may be helpful, but I suppose they may give you the 'ol, "we don't know, you would have to send it in and we would have to look at it" routine. Is it still under warranty?
