Re: Is this a RAM problem?
Can you borrow a stick from someone? Just seems unlikely that all 4 sticks would be bad.
Have you disconnected absolutely everything other than video? I've had mobo related issues with hdds and optical drives that prevented post before.
Gfx card reseated nice and tight?
Just tossing suggestions out there - 4 bad sticks just doesn't sound right.
EDIT: If all else fails remove it from the case and see if it posts. Make sure something isn't shorting in there.
