I just got an A8V-E SE motherboard and when I booted up I got 1 long beep followed by 2 short beeps. So I searched and found that it could be the ram. So I put the ram in slot 3 and it worked. I now have both 3 and 4 slots working. I tried slots 1 and 2 one at a time and the computer won't boot up. The first slots I tried were 1 and 3 to get dual channel. I have the latest BIOS update which is 1010. So is there something I can do to fix this or are those slots no good?
