Not a common power issue?

Viking Kong · October 14, 2013

So the pc that my mother and sister use has this problem. Try to power it on and the cpu, psu fan will start spinning and stop. Green light on the board, I've tried all the ram slots, I've disconnected the 4 pin, 24 pin, psu, 6 pin pci-e and plugged them all back in several times, reset cmos etc. It's done this before and I just unplugged everything and plugged it back it and it came on after 2-4 tries and worked for a couple months. I don't know what could be causing this.

What should I try?

Amd Athlon 5600

Asus MZN SLI Deluxe mobo

1 GB of OC

7900 GS

600w OCZ psu

It could be dead psu. Does it shutdown in middle of something or just don't start after cold boot?

Doesn't shut down, it's cold boot.

I think theres something wrong with mobo itself. I don't know excatly what. My old mobo did something similliar where it sometimes crashed to POST screen and continued after several reboots and disconnecting power cord for few mins. It did it with old CM psu and new Thermaltake psu.
