Katie Louise, you should tell us more about the exact beeps.One long and two short beeps, and a blank or unreadable LCD are indicative of either a bad mother board, a bad LCD, or bad memory modules. I would start by attaching an external monitor and see if it makes a difference. After that, pull the memory modules and reinsert one module at a time. Make sure that it is properly seated. If none of this works, you probably have a bad mother board. Hoe this helps, good luck.
