Try re-seating the CPU.

Make sure your CPU cooler is not on too tightly, this can bend the motherboard and cause loss of contact with pins.

Yeah I reseated CPU last night still nothing, worth to try again and check for bent pins and stuff? Also how tight should my cpu cooler be

A matter of experience and feel.

My general experience is that when using a full size screwdriver to use only the tips of my fingers to tighten. Things in a computer generally do not need to be tightened until they physically stop turning.

If you can see the board edge on, you can often see the bowing caused by too tight of a cooler. Quite common with LGA1700.

Also have to make sure you are using the appropriate mounting hardware with your cooler.
