intel dp67bg code 27 error

so the error code is for memory configuration, stated in the manual.

system specs are as stated in my spec list.

so the problem started about 3 weeks ago, i turned on my machine to be greeted with no boot screen just a loop mobo gets to code 27 then restarts repeatedly.

now if i pull the power lead, let the power drain and then plug it back and and power up it boots first time, every time, if i power down and restart without pulling the power it just loops on code 27.

what i've done since then.

stripped out case completly down to the bare bones.
cleaned out everything
checked all memory and ram, used mem test on all sticks indivdually, ran 10 passes per module.
made sure all the contacts were clean and free of dust before carefully reseating the memory.
checked to make sure nothing was in contact with the back of the motherboard, ie loose screws or something like that.

had kingston ram previously where the problem first happened, since then bought a new psu the one listed on specs, and new ram, 2 x 4gb corsair vengence.

and the problem is still present.

motherboard is probably around 4 months old now and i've been very carefull with it.


no overclocking done either this is litterally a stock system, so i can rule that out already.

the only thing i can replace now is the actuall case, which isn't out of the question.


so having said all that does anyone have any idea's? i'm in no real rush my computer works it's just annoying having to reach around to the back of my machine to pull the plug before i turn it on.

new psu and ram did resolve it, just took a restart and bios reset after the change for it to realise.
