I have the same issue. constant beep, beep never ending on boot. i can get to the repair windows by using the fn+esc key but it starts loading and goes back to the beep. can not get it to boot from the cd. history, this started about 3 weeks ago and i was able to get the system up. when i did it appeared the key board was bad so i replaced it. worked great for a week or so then boom, back to the same issue.
