Asus p8z68 (-v pro) trouble POSTing)

Hi everyone,

I built a new pc around 5 months ago, and all was running smoothly. However during the last month, sometimes- not always - when I turn the pc on, the motherboard does not post, as in no beep at all. Then it turns off, pauses for between 2 and 5 secs, and then starts up and always posts fine this second time. It's at most an inconvience i think, but does anyone know if it is damaging my system (as the pauses have been getting slightly longer each time I think), or how to solve it.

Thanks :)

Sounds like it may be a failing power supply or maybe the mobo, I'd try and get a different PSU and test with it

It sounds like your motherboard's battery might be going bad. Are you turning your computer's PSU or its power strip off between boot-ups?

Double pump from cold-start is actually normal depedning on how the system is configured (soem settings need a power cycle to be disabled/enabled). I would not worry about this.

Thanks Raja so much. I am overclocked (if that makes difference).

Is there a way I can stop this (reconfigure the settings). I boot up about once or twice per day normally, and does this count as a cold boot ( psu cable never removed or mains power never turned off).

Might try just a tad extra vCore to see if it boost into startup

This has nothing to do with Vcore.

Some fo the settings need a double-pump - the clockgen, and disabling some of the CPU features etc. As I said earlier, would not worry about it.
