Dimension 8300 RAM?Motherboard

[cadsys]

I installed (2) 1gb cards that I bought from dell onto my computer and now it won't boot up at all . I removed the new memory cards and the computer still won't boot. Dell customer service says that I need a new motherboard. Does this sound correct? I'm not sure that the customer service agent undersood a lot of what I was saying. Are there any home checks I can do? I checked all of the connections inside the computer and they are OK. Please help! I'm a computer novice.

Thanks, cadsys

Do you know which type of RAM does your motherboard supports. Is it DDR1, DDR2 or DDR3. Because the incompatible RAM can affect your motherboard. But if you sure that you had the right RAM then I believe that there can be some connection issue. You will have to explain the Dell person properly about your fault.Because if it is under warranty then it will not cost you anything.
