Suddenly deaad imac

I'm a new user, so forgive me if I came to the wrong palce. My imac suddenly died. Tried turning it back on, nothing. Unplugged it, heard three beeps then nothing. Anyone have any ideas?

RE: Dead imac

This is what the service manuals says about those 3 beeps:

One Beep: No RAM is installed or detected.
Two Beeps: Incompatible memory is installed. (The iMac ships with PC-100 SDRAM and does not accept SDRAM SODIMMs or EDO memory).
Three Beeps: No RAM banks passed memory testing.
Four or Five Beeps: Bad checksum for the remainder of the boot ROM. The ROM (which is located on the processor module) is bad.
