This really is a strange issue.
Suddenly our second PC doesn't respond to the start button (this already happened a week ago).
The Motherboard green led is on.
I have:
- Connected another power supply, still doesn't start.(The donor power supply did have another 4 pin 12v MOBO top left connection but that shouldn't be a problem)
- Checked If the button is broken (when pressed the Power supply gives another high pitched tone than when idle. Also manually connected the pins together with metal)
- Checked the little motherboard battery, have replaced it, still doesn't start, then put the original back on it.
- Started the pc without connecting anything on it.
- Removed the graphics card and tried it.
- Changed the power cord.
The most strange thing about it is when I brought it back to the pc dealer, it just started again!
So they could not find anything strange about it. But I knew that not finding any problem would make it return.
Now some days later... the same issue.
The only thing that could be different at the dealer is their power grid, I presume, So I went and tested the pc at the neighbors house but still the same.
The night before this occurred for the first time there was a lighting strike not too far away.
But all the other PC's are fine. So that may not be the issue.
I have build Pc's before so I am not a total noob.
What do you guys think?

Motherboard
ASUSTeK Computer INC. P8H67-M LX (LGA1155) 30 °C
Graphics
1024MB ATI Radeon HD 5400 Series (ATI AIB) 40 °C
Storage
OS:
238GB Samsung SSD 840 PRO Series ATA Device (SSD) 29 °C
931GB Western Digital WDC WD10EALX-009BA0 ATA Device (SATA) 33 °C
Edit:
1. Changed the power supply.
2. The 12V ATX on the corner of the MOBO is connected, the PC ran fine with the new PSU, it's the next day that it fails to power up again (until it stands for 24-48 hours without power, then it starts and runs, untill it fails to start the next day...the cycle goes on)
3. I have connected the PWR SWTCH pins manually to jump start it, the same, so its is not the power button either.
Like another member mentioned: Some of the capacitors of the motherboard might have been depleted.
The PC is now at the dealer.
I'll keep you updated.
