Have you tried booting with a *completely* minimal setup (no fd, dvd etc.)?

Could it be a faulty PSU?

You can short the green wire with a ground wire (ATX 24-pin plug) and fire up the PSU. Then you can measure the voltages on the 3.3, 5.0 and 12.0V rails and check if anything is out of the ordinary.

Well, I got it up again. Yanked out one stick of my HZs and it posted. Loaded fail-safe settings and booted.

So my question is, what is the issue? I usually have my black pis installed 2x2gig sticks. The first issue occurred and I put in my 2x1gig sticks of HZs. Someone suggested pulling a stick, and it boots now.

So are my ram slots going bad?
