So I'm having strange issues with ram posting. This is a friends build so sorry for my lack of complete knowledge of it. Asrock 970 Extreme 3 motherboard. Generic Mushkin? DDR3 1333 ram 2x 4GB sticks Geforce 660 Ti graphic card Seasonic 650W power supply AMD Phenom II 965 Now when I turn the computer on without RAM installed it does the standard 3 long beeps. I put the RAM in it does no beeps. The computer starts up and everything seems to be running optimally. Which leads me to believe it isn't the PSU or the CPU. I've tried both sticks in the slots and every time I stick them in I lost the no RAM beep. But then I don't get the no GPU beep that should I should be getting. This leads me to believe the RAM is bad. Problem is it's both sticks and they were working fine about a week ago. I don't want to go out on a limb and tell my friend to buy more RAM because I'm not sure it's the problem. I've switched out the motherboard with same everything else and had the exact same problem where the ram would beep when it wasn't in. I'd put the RAM in and it wouldn't beep. But sometimes on the other motherboard I would get no beep at all even if the RAM wasn't in there. I'm at a complete loss as to what the problem could be at this point. Don't want to tell him to buy something when I can't be sure what the problem is. Could the PSU be bad? Could the CPU be bad and only posting at certain times? Just need some advice from people who are more knowledgeable at this than me.
