I woke up today to a computer that will turn on for a few seconds, but then shut down. No beeps. I can tell from sound and sight that both the power supply is working and the motherboard receives power both when turned off (passive yellow light) and when on (additional lights turn on).
So I started pulling components to see if I could identity the root cause.
- USB connections
- Drives
- Video card
- Memory
Identical behavior.
I pulled the CPU and the behavior is similar, but it tries to turn itself back on every few seconds after failing the last attempt.
Suggestions? I think it has to be one of the CPU or motherboard, but I'm at a loss as to how to identify which one. Unfortunately I don't have any parts laying around of the same CPU design to swap things around and test.
Thanks in advance
