First off this is my first build so try to bear with me. I've been following the newegg tutorial here, but did not receive a beep when powering up for the first time. I am running an i5-3570k on an ASRock Z77 Pro4 Mobo with Patriot 2x4GB DDR3 1600 RAM (it's on the compatibility list). When I remove the RAM sticks and power it up, I receive 3 long beeps which I've read indicates a memory issue. When I plug in any stick of RAM and try, I get no beeps and no output on my monitor (fans and everything else do run). I have tried both sticks in all 4 slots to no avail. I left it running with no RAM for about half an hour and the CPU did heat up so I'm assuming that it is working fine. At this point I think the problem is either with my RAM or Mobo, which is more likely?
