Actually, without a speaker attached, the lack of video doesn't tell you 
much. It could be motherboard, CPU, RAM, or video card. It could even be 
the monitor. Though I agree that RAM probably is the most likely cause, 
in the absence of other evidence.

The beep codes are dependent on a functioning CPU to execute the POST 
routines in the BIOS, so you haven't ruled out the CPU as a cause. (I 
think with some motherboards, the POST routines are also dependent on RAM.)

At this point you'll have to do a component swap - either trying a 
different motherboard, or different CPU.
