If the schools IT have already tried replacing the RAM then it could be the processor module or logic board. To me it just sounds like bad RAM. See the beep error chart below. I've had 3 beeps in the past when I forgot to put the RAM back into a rev B, and 5 beeps when the processor module on a 333 was stuffed. Steve Bell Error Beeps If you hear from one to five error beeps at startup with no boot chime , you have a hardware problem. 1. Do you hear one error beep at startup? Yes: Follow these steps to resolve the problem: - Reseat the SDRAM and try again - If no SDRAM is present, install a known-good SDRAM SO- DIMM in the top slot and try again. - If DRAM is present, replace it (one DIMM at a time, starting with the top DIMM slot) with a known-good SDRAM SO-DIMM. No: Go to next step. 2. Incompatible RAM is installed. Do you hear two error beeps at startup? Yes: Verify that only SDRAM SO-DIMMs are installed and not EDO memory. (The iMac ships with SDRAM SO- DIMM memory and is not compatible with EDO DIMMs.) No: Go to next step. 3. Bad RAM. Do you hear three error beeps at startup? Yes: Replace the existing SDRAM one DIMM at a time (starting with the top DIMM slot) with known-good SDRAM SO-DIMMs. No: Go to next step. 4. Bad ROM. 5. Do you hear four or five error beeps at startup? Yes: Follow these steps to resolve the problem: - Reseat the processor module and try again. - Replace the processor module and try again. - Replace the logic board. -- The iMac List is sponsored by <http://lowendmac.com/> and...
