I have recently installed an Asus P8P67 deluxe into my original system. It works fine except for one issue. If the power has been switched off for about a minute or more (at the wall socket or at the power supply switch) then when switched back on it fails to power on when the PC's power button is pressed. Switching the power off until the green light fades on the board then restoring power then cause it to work but the bios has been reset and requires reconfiguring. Once configured and restarted all works as expected.
Orginally I was overclocking but for testing I simply change a fan setting so I can tell if the bios was reset. The problem is therefore easy to detect and repeat, it is not caused by overclocking or any operating system considerations. My only thought at the moment is the power supply. I am using a Zalman 500W ZM-500HP which worked fine with the previous mobo. It works fine with this new system once running, including overclocked CPU, a decent graphics card, 4GB memory etc. Its been in use for over 2 weeks without unexpected reboots, crashes or similar glitches, except when powered down as described above.
Is it possibly the mobo that is at fault? I have been unable to find others reporting a similar problem.
Any help gratefully received.
