Answer to: error 2NVD/1/4 2103In my circumstance, I don't accept this answer. My iMac G5 also gave the description 'Video RAM error detected' for this code. Computer booted from the Apple Hardware Test CD; otherwise no boot even in safe mode. In the extended Hardware test, logic board, memory, and mass storage all passed. Same results occurred twice. This computer was re-capped with most extensive kit about a yr ago, and power supply about 2 yrs ago. So the code probably means what it says: a video RAM problem. Question is: can be repaired? My company uses VLSICs and have some people skilled in SMT repairs, but still would have to find the right chip.
