My home PC is giving me some trouble, it's not booting up properly.
The power cycles on and off continuously. It doesn't show any signs of activity and only turns on for about 3 seconds before turning off for one, then repeats this cycle continuously. I have bench tested the power supply and that seems OK. It stays on when PS ON is held low. I've also scoped the rails on the outputs and they seem reasonable when under normal load, 12V at 12.2V, 5V at 5.09V, 3.3V at 3.37V. I'm thinking it's the motherboard, which is a Gigabyte Z97X-UD3H.
Does anyone have any experience of this issue?
Have done the obvious, like disconnecting all peripherals and drives, all fans, and running with only one stick of RAM. Will try another PSU just in case, also need to reset the CMOS or maybe use the backup BIOS flash on the board (apparently it has two).
Took power supply apart (EVGA NEX650G), no bad capacitors visible.
