I suspect an over heated cpu. I replaced the OEM cooling unit on the cpu and restarted. Initially, the fan did not turn. The system attemped to boot for about 45 seconds, then shut down. I removed the fan again and checked the cpu and socket. Other than the cpu being very hot, everything looks ok. I reinstalled and attempted a restart. The fan turns, but I don't get a video indication and I don't see any disk activity. After about two minutes, a red LED turned on. Is there a method of troubleshooting to confirm the board and cpu are good?
Thank you in advance for your assistance.
