Thanks for the reply smorizio, yes the BIOS is current, my RAM passes any tests I can throw at it. The entire system runs flawlessly but I'm having this odd once every now and then problem with powering up. I can't actually reproduce it on demand, it just happens when it happens. I am RMA'ing the video card since it's temperatures don't seem right to me, it doesn't overheat but it's idle temp is a bit too high for my liking. I wish this problem was more an all the time thing so I could doagnose it but unfortunately it's so random I can't figure it out. It seems to only happen when the PSU is completely cold, as in has been sitting overnight when it does happen but it's not guaranteed to fail either as it's been booting up cold fine for the past week until this morning.
