Last week I thought my board had killed one memory stick (sitting in the second blue slot ) I tried all kinds of different things (higher voltage, lower timings) but it would not boot, the other stick was working just fine. So I tried it on my friends DFI infinity 975 and the "dead" stick posted just fine. Came back home popped it back in and it was working, ran orthos for 10 hours at stock speed and everything was fine.
Yesterday I shut down my computer; this morning it refused to boot. I wasn't getting usual 3 beeps (no memory error) but the board was not posting either. It seemed like it was restarting itself every 2-3 seconds. Took one memory stick out now it's posting again.

Did anyone experienced anything like this before?
