[Novalug] Hardware problem

[Mike Shade]

Hard drives will spin up with just power applied, nothing else.  You're 
probably just not hearing it spin up, or it's dead.  Doesn't matter, 
that's a secondary problem.

The motherboard is toast.  To confirm this, remove the CPU and RAM.  
Booting should at least give you a beep or two to signify that there's 
no processor detected. (if it's the CPU that's failing and keeping the 
machine from POSTing).

If you get the same behavior with the CPU and RAM removed, you can be 
sure of a motherboard problem.  When the motherboard went, it may have 
also taken the RAM and CPU with it, so you'll want to test those before 
investing in another HP motherboard.
