Sounds like you pooched your CPU. Need a new logic board. OR if you dropped this machine before this started you could have knocked the RAM loose if you're hearing a single beep every 5 seconds repeating.

The beeps are to tell you what's wrong, let us know what you're getting for a possible fix:

1 beep = no RAM installed

2 beeps = incompatible RAM types

3 beeps = no good banks

4 beeps = no good boot images in the boot ROM (and/or bad sys config block)

5 beeps = processor is not usable
