From the symptoms you describe, I am more 
inclined to think that your motherboard (SATA) is 
having a problem.  Could also be a problem with 
the SATA disk drive.
Go to the web site for the manufacturer of the 
motherboard and see if they have a list of bios 
beep-codes - or try google for the information.
