Continuous Beeping: Memory or video problem
Explanation: The system is producing constant beeping in no specific pattern, or a fast "ringing" sound
Diagnosis: This is usually caused by a problem with the system memory, or possibly the video card. The memory is more likely--the system complains long and loud if it can't find any usable memory, as there is no way to even start the boot process when this is the case. The motherboard itself could also be the problem.
