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
Your RAM is bad. Make sure you push the RAM firmly until you hear a snap. If that still does not work, you need to purchase new RAM.
