Breadboarded computer keeps cycling on and off without booting
Got all the parts put together and into the case, but it wouldn't boot. I took everything out and breadboarded just the CPU, PSU, CPU fan, and the Mobo to see if it would give me the missing memory beeps. Unfortunately it still cycled on and off with no beeps.
When it cycles on and off, the LEDs light up, the fan starts, the number code display on the mobo says 15, the LEDs go dark and the fan stops. Then it starts back up again. Is one of the parts faulty? This is my first build so I'm really confused and frustrated. Any help or suggestions would be awesome.
