Ok so I built new computer a few days ago and it has been up and running with absolutely no problems. I wake up this morning and try to turn it on and it gives me the three beeps indicating it's not detecting my RAM. I've opened it and moved the RAM over to the other slots on the mobo and made sure they are firmly in place and it still does the same thing. I'm using an Asus P8P67 pro B3 mobo and 8gb DDR3 G-skill 1600 mhz RAM. Please help! Thanks.
