My iMac makes a continuous beeping noise and a blank screen.

My 2007 iMac is making beeping noises and it's just a grey screen. Nothing is happening. I've tried to restart and unplugged it and still does it. Does anyone know what is wrong and can I fix it myself? Thanks

iMac, OS X Mountain Lion (10.8.5)

Beeps on startup:


1 beep = no RAM installed

2 beeps = incompatible RAM types

3 beeps = no good banks

4 beeps = no good boot images.

5 beeps = processor is not usable
