Did you test the RAM with all 4 sticks in or one at a time in the slot in which it was in?
I tested all four sticks of RAM in all four slots at first, and it spat out a bunch of errors within the first pass on two occasions. Then I began testing each stick one by one, doing four passes each, but all in the same slot. No errors occurred when doing those tests. I'm working on testing each stick individually in every slot one by one right now, which will hopefully bring something up.
Any idea which stick tested bad?
No clue. As of yet I haven't had any errors pop up when testing any of the sticks by themselves.
Do you have another PSU to swap?
Yes. Actually I have a brand new Antec earthwatts 650 watts in the system as of right now that I'm using for all the testing since I thought originally that the power supply might be a problem. Sorry I forgot to mention that!
When the system would not start, was it a complete power failure, i.e., any power getting to the system -- lights, fan, etc...?
On first attempt to start it, it would start and then immediately (less than a second) shut itself off. The fans would kick on very quickly and the case lights would turn on, but shut off again immediately. On repeated attempts, nothing seemed to happen at all. This only happened when the graphics card was attached. I could run any other combination of components I could think of but as soon as the graphics card was attached it wouldn't boot. I tried both the BFG and Antec power supplies and I made sure the card was properly seated and plugged in, but it wouldn't start as long as the card was in.
Not too sure about when at desktop or under load since I've had it on Memtest all day, but in Memtest the cpu temp hasn't gone past about 45c if I remember correctly. I think the max temp for this cpu is 61 c if my memory serves me correct.
I'll get right on running speccy. I'll post back as soon as I can.
