Hi there, I have an early ASUS P8P67 Pro that WASN'T returned to get the SATA 3Gbps thing sorted (I didnt care as I dont use those ports). Since new though the unit has an odd habit: Every time I unplug the unit from the mains, and then plug it in, turning it on it refuses to POST and the red memory led stays lit. I turn the PC off, turn it striahgt back on again, and it booted fine but when POSTing would say 'overclock failed' (I overclocked it to 4.5ghz using Bit-Tech's isntructions) and I needed to enter the overclock settings all over again. I updated the BIOS to the latest version (non-beta) in March but this made no difference. I then updated it to the latest non-beta version (1704 I believe?) at the weekend and now the unit performs this strange quirk of behaviour every time i turn it on, whether the mains has been disconnected or not. Has anyone else come across this, or does anyone have any ideas? It's really more of an annoyance than anything else but I would like to have a resolution of some kind, if anyone can help! Cheers.
